Marathon Fusion Mercury to Gold: What Ancient Indian Rasashastra and Modern Science Reveal
Indian Rasashastra, Acharya Nagarjuna, and the Ancient Tradition of Gold-Making from Mercury
It Is Time to Revisit the Legacy of Ancient Indian Knowledge and Science
Most students of Ayurveda today are likely to be familiar with the text book written by Professor Siddhinandan Mishra sir. The history of India's intellectual traditions is exceptionally rich. Our ancient texts, including the Vedas, Upanishads, and various Shastras, contain numerous ideas concerning nature, medicine, metals, and different scientific concepts. However, the presence of a description in an ancient text and its confirmation through modern scientific experimentation are two distinct matters. Nevertheless, the systematic study of these texts remains essential for understanding the historical development of human knowledge.
India has been a land of knowledge, philosophy, medicine, and scholarship for centuries. However, during prolonged periods of foreign rule, Indian literature, culture, traditions, and intellectual heritage suffered various forms of damage. Invasions, colonial policies, and cultural neglect affected numerous ancient manuscripts, institutions, and knowledge traditions. As a result, a tendency sometimes developed to interpret India's knowledge systems primarily through the frameworks of Western intellectual traditions.
Even after India attained independence, the preservation, advancement, and scientific reassessment of its heritage did not always receive the attention they deserved. Significant changes took place in science, medicine, and education, yet concerns regarding the neglect of India's traditional knowledge continue to be expressed. Governments and institutions have changed over time, but the challenge of securing appropriate recognition for our ancient intellectual heritage has not entirely disappeared.
Modern Laboratories and the Ancient Indian Tradition of Rasashastra
When claims concerning the production of gold in a laboratory in San Francisco receive widespread attention in the news media, it is natural to ask why Indian medical science, Ayurveda, traditional chemical knowledge, and ancient intellectual traditions should not also receive equally serious consideration.
Scholars working in Indian medicine and traditional sciences often face the challenge of demonstrating the scientific relevance of their knowledge. At the same time, modern scientific research investigates questions that may, in certain respects, resemble ideas found in ancient literature. Therefore, the need of the hour is to study the processes described in Indian texts impartially and evaluate their claims according to contemporary scientific standards.
Some subjects being investigated in laboratories today have conceptual parallels in ancient Ayurvedic and Rasashastra literature. Our revered Gurudev, who passed away a few days ago, possessed profound knowledge of this discipline. His learning and experience inspire us to appreciate the importance of this intellectual tradition and the need to preserve the knowledge accumulated by generations of scholars.
I would like to present several important references and considerations on this subject.
1. The Art of Producing Gold from Mercury: An Ancient Indian Heritage
The concept of producing gold from mercury, known in Sanskrit as Parada, has been discussed since ancient times in the Indian tradition of Rasashastra. Acharya Nagarjuna is regarded as one of the principal figures associated with this tradition. Rasashastra literature attributed to or associated with him discusses mercury, metals, chemical processes, and various aspects of metallic transmutation.
The contemporary discussion of the possibility of producing gold from mercury in modern scientific laboratories provides a new context for the historical study of Indian Rasashastra. It also invites us to examine the similarities and differences between traditional alchemical thought and modern nuclear science.
Acharya Nagarjuna: A Great Master of Indian Rasashastra
Acharya Nagarjuna occupies an important place in the history of Indian Rasashastra. He is regarded as a prominent figure associated with mercury processing, Rasakriya (alchemical operations), and the tradition of Dhatuvada, or metallic transmutation. Numerous texts and intellectual traditions associated with the name Nagarjuna appear in the historical literature on Indian alchemy and chemistry.
Some important texts and references associated with this tradition are as follows:
1. Rasarnava: This is an important text in the Indian Tantric tradition of Rasashastra. It discusses mercury, sulphur, metals, Rasasiddhi (the attainment of alchemical accomplishments), Dehasiddhi (the perfection or transformation of the body), and Dhatuvada. Its textual tradition is associated with Nagarjuna and various other Rasasiddhas, or accomplished practitioners of alchemical disciplines.
2. Rasaratnakara: This title appears among the well-known alchemical works associated with Nagarjuna. The literature discusses chemical operations, metals, minerals, and the use of mercury. However, historical caution is necessary because several works bearing this or similar titles exist, and their authorship, textual histories, and dates are not always conclusively established.
3. Kakshaputa Tantra: This work is also mentioned within the textual tradition associated with Nagarjuna. It discusses alchemical operations and subjects related to the attainment of specialised accomplishments.
4. Yogashataka: This title also appears in discussions of works associated with Nagarjuna. Examining its authorship, textual relationships, and historical identity is important for understanding the development of Indian medical literature.
A serious study of these texts and the traditions associated with them can help us understand the historical development of Indian Rasashastra. Such research should include the examination of original manuscripts, critical editions, historical context, and the distinction between established facts and later traditional attributions.
2. Gold-Making from Mercury: The Dhatuvada Tradition of Indian Rasashastra
In Indian Rasashastra, mercury is regarded as an exceptionally important alchemical substance. Within this tradition, the uses of mercury are broadly associated with two principal objectives.
Dehavada: The traditional pursuit of bodily perfection, health, and longevity through mercury and other alchemical substances.
Dhatuvada: The traditional concept of transforming base metals into higher or more valuable metals.
Rasashastra literature assigns particular importance to the eighteen processes, known as the Ashtadasha Samskaras, associated with the preparation and processing of mercury. These procedures are traditionally understood as methods intended to make mercury suitable for various alchemical applications.
The same literary tradition refers to processes such as Bija, Vedha, Jarana, Marana, and Patana, along with various specialised apparatuses and operations. In the context of Dhatuvada, the intended transformation is not necessarily understood merely as a change in the external colour of a metal; traditional descriptions may also refer to a transformation in the metal's intrinsic nature.
The Rasasiddha tradition associated with Acharya Nagarjuna gives particular importance to the concept of achieving metallic transformation through mercury.
In this context, the following Sanskrit verse is often cited:
“सिद्धे रसे करिष्यामि निर्धारिद्र्यमिदं जगत्।”
English translation: “Having attained mastery in Rasashastra, I shall strive to free this world from poverty.”
The verse expresses an ideal in which the pursuit of alchemical knowledge is linked not merely to personal achievement but also to the welfare of humanity. Its precise textual source and attribution should, however, be verified against an authoritative edition before it is treated as a historically authenticated quotation.
The broader ethical message remains significant: knowledge and disciplined inquiry should ultimately contribute to human welfare and the betterment of society.
3. Are Complete Instructions for This Process Available in Ancient Scriptures?
This is a particularly intriguing question and an important subject for scholarly investigation. Numerous Rasashastra texts describe the processing of mercury, metallic transmutation, Bija, Vedha, and various specialised instruments. Nevertheless, it does not necessarily follow that every claimed accomplishment is accompanied by a simple, sequential, and universally applicable experimental procedure.
Within this tradition, certain forms of knowledge were preserved through the Guru–Shishya Parampara, or teacher–disciple lineage, initiation, practical experience, and specialised technical terminology.
According to traditional interpretations, knowledge of certain specialised procedures was sometimes transmitted only to qualified disciples. The reasons commonly associated with such restricted transmission include the complexity of the experiments, the need for specialised training, and concerns about potential misuse.
At the same time, the historical existence of a description does not establish that the process was experimentally successful. Nor does the absence of an easily accessible procedure prove that a secret method must have existed or worked.
The effectiveness of any particular process must therefore be evaluated through evidence, reproducibility, independent verification, and appropriate scientific testing. Traditional accounts deserve serious historical examination, but their practical claims must remain open to objective investigation.
4. Modern Science Is Also Investigating the Possibility of Producing Gold from Mercury
Let us now consider some important developments in modern science and the claims associated with them.
CERN Experiments: 2015–2018
At CERN, the European particle physics laboratory, scientists studied the production of gold nuclei during interactions involving lead nuclei in the Large Hadron Collider (LHC).
According to an analysis published in 2025, experiments conducted during the LHC's Run 2 period, from 2015 to 2018, produced approximately 29 picograms of gold nuclei across the accelerator's four major experiments. This is an extraordinarily small quantity. The gold nuclei existed only briefly before interacting with accelerator components and breaking apart. They were not collected as a usable quantity of metallic gold. [Source: CERN and the ALICE Collaboration, 8 May 2025.]
This finding is an important example of nuclear transmutation: the transformation of one chemical element into another through changes in its atomic nucleus. It demonstrates that a process once associated with the historical pursuit of alchemy can occur under specific nuclear-physics conditions, although it does not establish a commercially practical method of manufacturing gold.
The Claim by US Company Marathon Fusion: October 2026
On 23–24 October 2026, several news organisations, including Business Standard and NDTV, reported a claim by Marathon Fusion, a US-based fusion-energy startup headquartered in San Francisco. The company stated that it had achieved the conversion of mercury into stable gold using neutrons generated through nuclear fusion.
According to the company, its proposed process involves the following nuclear pathway:
The mercury isotope mercury-198 is exposed to high-energy neutrons.
Under suitable nuclear-reaction conditions, mercury-197 may be produced.
Mercury-197 is radioactive and can subsequently undergo electron capture, transforming into gold-197.
Gold-197 is the stable isotope of naturally occurring gold.
Marathon Fusion has claimed that its production rate exceeds a benchmark associated with CERN by a factor of ten. However, this comparison is a company-reported claim and should not be interpreted as an independently established result.
An important distinction must be made here. Proposing a technical process, demonstrating it experimentally under controlled conditions, obtaining independent scientific verification, and achieving commercial-scale production are four different milestones.
The company's claim therefore requires independent scientific scrutiny. Important questions include the actual quantity of gold produced, the purity and isotopic composition of the recovered material, the efficiency of the process, the energy and capital costs, and the feasibility of scaling up production.
Until adequate experimental data and independent verification are available, the announcement should be treated as a potentially significant scientific claim rather than a conclusive demonstration of commercially viable gold production.
The development of practical fusion-energy systems also remains a major engineering challenge. Consequently, projections concerning large-scale gold production should be distinguished from demonstrated industrial capability.
5. Does Modern Scientific Research Bring Renewed Attention to the Importance of Indian Rasashastra?
Certainly, these developments create an important opportunity to revisit Indian intellectual traditions through historical research and scientific inquiry.
Modern science has established that one chemical element can be transformed into another by changing its atomic nucleus. This process is known as nuclear transmutation.
Indian Rasashastra, meanwhile, contains numerous concepts relating to Dhatuvada, the processing of mercury, and metallic transformation.
The historical and conceptual relationships between these two traditions merit investigation. However, it is essential to recognise that not every process described in ancient Rasashastra corresponds to modern nuclear transmutation. The two traditions must be compared on the basis of their actual principles, procedures, historical contexts, and supporting evidence.
Traditional alchemical operations may involve heating, chemical reactions, amalgamation, mineral processing, changes in colour, or other material transformations. Nuclear transmutation, by contrast, involves a change in the atomic nucleus. Similarities in the intended outcome do not, by themselves, establish equivalence between the underlying mechanisms.
Why Is It Necessary to Reassess Acharya Nagarjuna's Contributions?
It is not sufficient merely to remember Acharya Nagarjuna as a historical figure. The Rasashastra tradition associated with his name encompasses an extensive body of literature concerning Dhatuvada, Dehavada, the processing of mercury, and a variety of chemical and alchemical operations.
This literature deserves systematic collection, critical textual analysis, historical interpretation, and evaluation from an appropriately evidence-based scientific perspective.
Some important academic references relevant to this subject include the following:
“Introduction to Rasashaastra: The Iatrochemistry of Ayurveda” — African Journal of Traditional, Complementary and Alternative Medicines, 2011. This study is a useful starting point for understanding the development of Rasashastra and the traditional role attributed to Nagarjuna.
“Critical Review of Rasaratna Samuccaya: A Comprehensive Treatise of Indian Alchemy.” This reference concerns the examination of Indian Rasashastra literature and its historical and alchemical context. The complete bibliographic details should be checked before citing it in formal academic work.
V. Deshpande (1984), “Transmutation of Base-Metals into Gold as Described in the Text Rasarnavakalpa and its Comparison with the Parallel Chinese Methods,” Indian Journal of History of Science. This reference concerns the historical study of metallic transmutation in Rasarnavakalpa and its comparison with parallel Chinese traditions.
Patricia Southoff, “Rasa and Rasaśāstra,” Oxford Bibliographies. This is a reference for exploring the historical development and scholarly study of Indian Rasashastra. The author's name, title, and publication details should be verified against the relevant bibliographic record.
These references point towards a longstanding literary and intellectual tradition in which metallic transmutation was an important subject of discussion. The idea did not originate with contemporary news reports.
Nevertheless, each reference must be checked against its original publication, including its precise title, authorship, publication date, and conclusions. Historical evidence for the existence of an idea must also be distinguished from experimental evidence that a particular process successfully achieved its stated objective.
6. Will India Be Able to Give Its Ancient Chemical Heritage the Recognition It Deserves?
Scientific laboratories across the world are investigating nuclear transmutation, synthetic elements, nuclear technologies, and new materials-processing techniques. In this context, India has a compelling reason to undertake a serious, impartial, and scientifically informed study of its Rasashastra heritage.
Ancient Indian texts should not be dismissed merely as religious or historical literature. Their descriptions of apparatuses, processes, metallic treatments, and chemical concepts also deserve scholarly investigation.
The intellectual traditions associated with Acharya Nagarjuna and scholars such as Professor Siddhinandan Mishra deserve preservation, documentation, and further study.
Following the passing of Professor Siddhinandan Mishra, the question of how to safeguard traditional Rasashastra knowledge, rare manuscripts, and the accumulated experience of learned practitioners becomes even more important.
On one side, modern laboratories are conducting research into the transformation of elements. On the other, Indian Rasashastra preserves an extensive literary tradition concerning mercury and metallic transmutation. Understanding both requires freedom from prejudice, rigorous historical scholarship, and evidence-based scientific testing.
India should take pride in its intellectual heritage. Understanding the contributions of its Acharyas, preserving their writings, and transmitting their knowledge to future generations are collective responsibilities.
A comprehensive understanding of the history of Indian chemistry cannot be developed without examining a tradition in which mercury, metals, and various chemical processes have been subjects of sustained inquiry for centuries.
It is essential that we neither accept every traditional claim as a miracle without testing it nor reject ancient knowledge without studying it. Genuine respect for our heritage lies in preserving it, understanding its historical meaning, and evaluating its claims against scientific evidence wherever such evaluation is possible.
A Humble Appeal to Scholars:
Many scholars and researchers are working on various aspects of this subject. I respectfully appeal to all teachers, Acharyas, traditional practitioners, and researchers to contribute to this discussion through their knowledge, experience, research, and authentic references.
If ancient Rasashastra texts, rare manuscripts, and records of traditional experiments are systematically collected and studied, many important dimensions of India's intellectual heritage may become better understood.
Our objective should not be limited to glorifying the past. It should be to understand our heritage, preserve it for future generations, and establish its genuine significance through evidence-based research.
Respect for India's intellectual traditions becomes meaningful when preservation, scholarly investigation, and scientific evaluation are pursued with equal seriousness.
A Modern Scientific Development That India Must Not Ignore
A report published by The Economic Times on 23 October 2026, titled “Lab-grown gold to crash prices? San Francisco’s Marathon Fusion just turned mercury into yellow metal,” has brought renewed attention to the possibility of producing gold through modern nuclear technology.
News source: The Economic Times
According to the report, Marathon Fusion, a San Francisco-based fusion-energy startup, claims to have developed a process involving nuclear transmutation in which mercury can be converted into stable gold. The company has stated that its achievement exceeds a benchmark associated with CERN by a factor of ten.
However, an important qualification must be emphasised: the company has not publicly disclosed sufficient experimental data or the quantity of gold allegedly produced to establish the scale, reproducibility, and commercial feasibility of its claimed achievement. The possibility of producing gold economically on an industrial scale therefore remains unproven.
The underlying nuclear principle is scientifically understandable. Mercury-198 can, under suitable neutron-irradiation conditions, produce mercury-197, which can subsequently undergo radioactive decay through electron capture to become stable gold-197. Yet demonstrating a nuclear reaction is not the same as establishing a commercially viable gold-production industry.
The report also raises an intriguing economic question: if technological advances eventually make the large-scale production of gold possible, could the increased supply substantially reduce its market price?
That possibility deserves consideration, but it is premature to predict a collapse in gold prices. Production costs, energy requirements, radioactive by-products, processing and storage requirements, regulatory restrictions, and the actual quantity of gold that could be produced would all influence the outcome.
Nevertheless, this development raises a much broader question for India.
If modern laboratories are exploring the transformation of one element into another, why should India not place its own ancient Rasashastra literature at the forefront of systematic historical, scientific, and technological research?
India Must Lead the Study of Its Own Intellectual Heritage
The central issue is not whether India must compete with every modern scientific announcement. It is whether India can develop the intellectual confidence, research institutions, scientific infrastructure, and scholarly commitment required to investigate its own knowledge traditions with the seriousness they deserve.
For centuries, Indian Rasashastra literature has discussed mercury, metallic processing, specialised apparatuses, alchemical operations, and the traditional concept of Dhatuvada. The works associated with Acharya Nagarjuna and other Rasashastra scholars form an important part of India's history of scientific and technical thought.
These texts should not remain confined to historical references, traditional interpretations, or occasional public discussions. They deserve critical editions, accurate translations, manuscript preservation, comparative historical studies, and interdisciplinary research involving historians of science, Sanskrit scholars, chemists, materials scientists, and nuclear physicists.
India should establish a research framework in which its own intellectual traditions provide the starting point for inquiry, while experimental evidence determines which claims can be scientifically established.
This means making the Indian knowledge system a primary intellectual and research priority, rather than treating it as a secondary subject that becomes worthy of attention only when a comparable development is announced elsewhere.
Such an approach does not require the rejection of modern science or the uncritical acceptance of ancient claims. On the contrary, it requires India to develop the confidence to investigate its heritage independently, formulate research questions from its own texts, and contribute original findings to the global scientific community.
From Preserving Ancient Texts to Building Future Scientific Capabilities
India must move beyond merely celebrating its ancient achievements. Preservation is essential, but preservation without systematic investigation leaves much of a knowledge tradition unexplored.
A comprehensive national research initiative could include the following priorities:
Preservation of original manuscripts: Identify, catalogue, digitise, and critically edit ancient Rasashastra texts, including variant manuscripts and regional commentaries.
Verification of historical attributions: Establish, wherever possible, the authorship, chronology, textual transmission, and historical context of works attributed to Acharya Nagarjuna and other traditional scholars.
Scientific interpretation of traditional terminology: Examine terms such as Parada, Bija, Vedha, Jarana, Marana, and Patana in their original textual contexts rather than assuming that they correspond directly to modern chemical or nuclear processes.
Interdisciplinary research: Encourage collaboration among Sanskrit scholars, historians, chemists, materials scientists, and nuclear physicists to distinguish historical descriptions, plausible chemical operations, and claims that would require nuclear mechanisms.
Evidence-based experimental evaluation: Subject testable claims to appropriate laboratory investigation, independent replication, transparent reporting, and recognised safety standards. Any work involving mercury or radioactive materials must be conducted only in suitably equipped and authorised facilities.
Development of Indian research institutions: Support universities, national laboratories, and dedicated research centres that can investigate traditional Indian scientific literature while developing contemporary scientific capabilities.
International academic leadership: Publish findings in reputable peer-reviewed journals, make verified manuscripts accessible to researchers worldwide, and encourage Indian scholars to lead international discussions on the history of chemistry and alchemy.
Through such initiatives, India could transform its rich textual heritage into a stronger foundation for historical scholarship, scientific education, and original research.
The Indian Knowledge System Should Be at the Forefront
The achievement of a nation is not measured solely by the discoveries announced by its laboratories. It is also measured by its ability to preserve intellectual continuity, critically examine its historical achievements, and convert accumulated knowledge into new questions, methods, and discoveries.
When a modern company announces a possible route from mercury to gold, the appropriate response from India should not be merely admiration, scepticism, or a claim that ancient scholars had already accomplished the same thing. The appropriate response should be to investigate our own textual heritage, establish what the historical evidence actually demonstrates, and determine whether any testable propositions warrant further scientific research.
We should not confuse a traditional description of metallic transmutation with proof of nuclear transmutation. Nor should we assume that a modern announcement automatically validates an ancient account. The mechanisms, experimental conditions, and evidence must be examined independently.
At the same time, India must not allow its own intellectual traditions to remain inadequately studied simply because they originated centuries before the development of modern laboratories.
The Indian knowledge system should be a prime focus of India's intellectual and research agenda—not merely a subject of retrospective pride, but a living foundation for scholarship, innovation, and scientific inquiry.
Our ancient Acharyas deserve recognition through the careful preservation of their works, accurate interpretation of their ideas, and serious investigation of their contributions. Their legacy should inspire us to ask better questions, build stronger institutions, and pursue knowledge with intellectual courage and scientific integrity.
If India wishes to establish itself as a global centre of knowledge, it must invest not only in importing technologies and adopting discoveries made elsewhere, but also in investigating its own intellectual heritage and developing the capacity to make original contributions to the world.
The time has come to bring India's ancient knowledge traditions into a new era of research—one in which historical scholarship, indigenous intellectual perspectives, modern scientific methods, and independent verification work together.
Let us neither glorify the past without evidence nor neglect it without investigation. Let us preserve our heritage, place the Indian knowledge system at the forefront of our research priorities, and allow rigorous scholarship and scientific evidence to establish the true significance of our ancient traditions.
That would be a meaningful tribute to Acharya Nagarjuna, to the scholars and Gurus who preserved these traditions, and to the generations that will inherit India's intellectual legacy.
