This group focuses on the kinds of research published in journals such as the Indian Journal of History of Science, the e-Journal of Indian Medicine: EJIM, Asian Medicine, and History of Science in South Asia. The working group brings together scholars who study the history of science in South Asia before about 1800 and as discoverable from literatures in Sanskrit and other indigenous Indian languages. We take “South Asia” as an inclusive, non-political, socio-geographic term referring to the area from Afghanistan to Sri Lanka, from Pakistan to Bangladesh, and of course India. Discussions on the influences of South Asian cultures beyond these borders is also welcome, for example Nepalese or Tibetan influences on China, Sri Lankan influences on the Maldives, or Indian influences in South-East Asia. We broadly conceive of “science” to include all forms of systematic intellectual activity, as in the German “die Wissenschaft,” that covers most forms of academic scholarship. Theoretical discussions of the meaning of “science” in the South Asian context are welcome. The group meets monthly during the academic year. We welcome the presentation of individual and group work-in-progress, facilitated discussions of published articles and books, and focused reading sessions in Indic languages.
Tandulaveyāliya - An ancient Jain philosophical reflection on life
The Tandulaveyāliya is a relatively short philosophical treatise in the format of a dialogue on life in general between a master and his disciple, using the disappointments and sufferings of life as rational and emotional arguments to convince the pupil to take religious vows and lead a life dedicated to the right religion. With an uncertain dating between the fifth and seventh centuries CE, and an unknown authorship, it is a relatively short work. In a mix of prose and verse it is structured as a private question and answer session between Mahāvīra and Indrabhūti Gautama, his first gaṇadhara or chief disciple. In his discourse, Mahāvīra offers a disconcerting portrayal of the human body and critiques the superficiality of material life—characterized by eating, drinking, and reproduction. The text describes processes such as fertilization, early embryonic development, pregnancy, human anatomy, and various physiological functions. In one remarkable passage an attempt is made to calculate the precise amount of rice grains (taṇḍula) and other dietary elements consumed by a man who lives for a hundred years. This calculation gives the work its name, Tandulaveyāliya (Reflection on Rice Grains).
In this presentation, some of the underlying Jain philosophical and religious insights, which constitute its educative value will be discussed and ancient Indian insights in early human embryology will be contrasted with those in the age of MEM (modern established medicine).

Incurability as ‘disability’ in classical Āyurveda: The case of vision disorders
Tulika Singh (University of Alberta)
In classical Āyurveda, disorders become disabilities, marked by inauspiciousness and social stigma, only when they are entirely incurable. The medical literature considers all treatable conditions as ‘normal,’ and it is primarily the incurability of a condition that renders it ‘disabling’ for the body. This perspective stands in contrast to prevailing legal and normative discourses, which often perceive disorders as socially and legally disabling simply due to their existence. However, the early Indian medical perception of normality and disability is not centered on disorders or the body that possess them but rather on the potential for curability or incurability of the condition in the body.
To illustrate this point, this paper will discuss curable and incurable vision disorders and their connection to the perception of blindness in the literature. The first section will examine the causes and treatments of curable vision disorders, ranging from partial blindness (timira) to mature cataract (liṅganāśa), to demonstrate that even severe vision loss that can be cured is regarded similarly to any other eye ailment, and therefore is not considered a ‘disability.’ The second section will place importance on incurable vision disorders, highlighting that the physician is advised to neglect curing these conditions primarily because they are deemed incurable. Attempting to treat an inherently incurable condition may incur a bad reputation to the physician. Thus the incurability of a condition contributes to the stigma associated with it. This perspective provides us context for understanding occasional references to the inauspiciousness of blindness, viewing it as a disability in Āyurveda. It is not the disorder itself or the body possessing it but rather the intrinsic incurability of the condition that makes it a disability in medical thought.

A Contagion Theory in the Hārītasaṃhitā? The Chapter on upasarga
Dr. Vitus Angermeier (University of Vienna)
In studies concerning notions of contagion in pre-modern South Asia, the term upasargahas repeatedly attracted attention because it evidently refers to the transmission of diseases through bodily contact. Although these contacts are not always person-to-person, upasargais increasingly used, especially in the commentary literature from Cakrapāṇidatta onwards, to describe processes that are today understood as contagion. Sources consulted to understand the development of the term generally include the compilations attributed to Caraka, Suśruta and Vāgbhaṭa (between 150 and 700 CE), as well as later commentaries on these texts (from the 11th century onwards). The less noted Hārītasaṃhitā, usually thought to have been composed in its surviving form between 700 and 1000 CE, is generally overlooked in this context. In this talk, I will examine the use of upasarga in the Hārītasaṃhitā, as the text promises to fill a major gap by means of two particularities: Due to its date, this compilation can shed light on the developments that took place in the period between the writing of the earlier compilations and the later commentaries. And secondly, the Hārītasaṃhitā is the first medical compilation to contain an entire chapter (3.34 on upasargacikitsā, "treatment of infectious diseases") dedicated to the concerned concept.

Ancient manuscript fragments of the Carakasaṃhitāand their text genealogical relevance
Dr. Gudrun Melzer (Ludwig-Maximilians-Universität München) Dr. Philipp Maas (University of Leipzig)
Various modern collections of ancient Buddhist manuscripts contain fragments of works from other literary genres than Buddhist literature proper, such as medicine. Recently, Gudrun Melzer identified fragments of manuscripts containing the Carakasaṃhitā among these oldest attestations for the transmission of medical knowledge in writing. The ancient Caraka fragments, which can be dated to a period from the fifth to the eighth century CE, predate all other surviving manuscripts by more than a millennium. They thus provide a unique snippet view of the early transmission history of the oldest extant medical compendium. In the first part of this presentation, Gudrun will introduce the newly discovered Caraka fragments along with the current state of knowledge concerning their origin, their dating and context. In the second part, Philipp will discuss possible conclusions concerning the transmission history of the Carakasaṃhitā based on a comparison of the text version transmitted in the fragments with that of later Caraka manuscripts.

Dreams and Tooth-cleaning-sticks: Two Omens from Indian Tantric Traditions
Dominique Baur, M.A. (Heidelberg University), Dr. Daisy Cheung (Hamburg University)
Omens are present in many traditional Indian scientific knowledge systems such as Āyurveda and Jyotiḥśāstra. Although many scholars have surveyed omens in various texts and contexts, detailed studies are few. Within Jyotiḥśāstra, von Negelein has extensively studied Jagaddeva’s Svapnacintāmaṇi (1912), a compendium on dream omens. Zysk has systematically studied human marks (2016) and crow omens (2022) across knowledge systems. Within ritual studies, Geslani (2018) has focused on the ritual use of omens concerning kingship rituals. However, none of these works have addressed the place that omens occupy in Tantric traditions, such as Pāñcarātra, Śaivism and tantric Buddhism.
In our paper, we will investigate the dream (svapna) and the throwing of the tooth- cleaning-stick (dantakāṣṭha) as two common examples of omens in Tantric ritual. Drawing from sources in Sanskrit, Tibetan and classical Chinese we will compare, among other texts, passages from the Jayākhya-, the Viśvaksena- and the Paramasaṃhitā, the Niśvāsatattvasaṃgraha, the Śārdūlakarṇāvadāna, the *Svapnohana and the Svapnādhyāya. With a detailed study of these two omens we hope to provide more examples of intertextuality and to address the question of a common ‘cultural substratum’, as well as to shed light on omens as a new field of study.

Speaker: Dr Vijaya Deshpande Title: The Rasopaniṣad Abstract: I recently revised my earlier work on a Sanskrit alchemical text called the Rasopanișad. The Bhandarkar Oriental Research Institute, Pune, published it last year as Rasopanișad - A Discourse on Indian Alchemy. I will discuss some points related to this work such as what is this text about, why I selected it for a detailed study, why it is somewhat peculiar and what it tells us about medieval Indian chemistry and metallurgy. A series of five lectures on this topic were recorded by BORI. They are for a lay person who is new to the topic. They are accessible on the following link. https://bori.ac.in/infosys-a-p-videos/

Speaker: Dr Cristina Pecchia, University of Vienna and Austrian Academy of Sciences Topic: Ayurveda and Philology: Gangadhar Ray Kaviraj and His Legacy.* The wide spreading and popularization of Ayurveda makes it more urgent to gain a deeper understanding of the formative stages that led to the present configuration of this medical tradition. In this talk I will present the research project “Ayurveda and Philology: Gangadhar Ray Kaviraj and His Legacy”, which aims at exploring the interplay between Ayurveda and the Sanskritic culture during the colonial period. Its main focus is Gangadhar Ray Kaviraj (1798–1885), who was editor and commentator of the Carakasamhita. The project will study Gangadhar’s editorial and interpretative activity and his legacy in the making of modern Ayurveda, with special regard to practices and dynamics concerning texts and the context of their production. * The project is based at the University of Vienna and funded by the Austrian Science Fund (FWF)

Speaker: Dr Lisa Brooks, Killam Postdoctoral Fellow at the University of Alberta Topic: Classification, Coagency, and Care: Human-Leech Medicine in Early South Asia Abstract: Leeches and humans have a long history of medical entanglement. For over two thousand years and across a range of geographical and cultural spaces, leeches have been regarded by humans as a both a venomous nuisance and a medical technology. The oldest and most detailed surviving description of leech therapy is found in an early first-millennium Sanskrit treatise focused on surgery, theSuśrutasaṃhitā. In this treatise, non-venomous leeches are listed as a type of medical tool, an accessory or substitute sharp instrument (anuśastra) for surgical practice, and as the gentlest method of bloodletting. But the treatise also highlights their nature as living beings by detailing how a physician should interpret leech behavior and care for them. The way in which leeches and human-leech interactions are portrayed reveal a range of attitudes about physicians’ sensory expertise, the nature of leeches, and what constitutes medical agency or a medical technology. The talk will explore how textual representations of leeches challenge early ayurvedic classificatory schemes, and the ways that, in practice, leeches push against the notion of locating medical agency solely in the realm of the human.

Speaker: Lucy May Constantini Title: Understanding Text in Relation to the Embodied Practice of Kaḷarippayaṟṟ˘: investigating alternative methodologies Abstract: Kaḷarippayaṟṟ˘ is a martial art with an allied medical system that originated in South India in the Malabar region of what is now the modern state of Kerala. Its long and complex history includes a revival from near-extinction in the early twentieth century when a few practitioners gathered and systematised what knowledge remained, both practice and text. Malabar kaḷarippayaṟṟ˘ evinces a particular relationship between its inherited texts and lived practice. A kaḷarippayaṟṟ˘ gurukkaḷ (lineage-holder) carries the responsibility of preserving and transmitting the lineage, and, regardless of any reverence for inherited manuscripts, the final śāstric authority of the kaḷari resides in the gurukkaḷ’s body and practice. As such, written texts only partially represent a kaḷari’s śāstra, which is only complete when informed by the experience of embodied practice. To date there has been little academic enquiry into the texts of kaḷarippayaṟṟ˘, in part because of the inaccessibility of kaḷari paramparā manuscripts, which introduces further complication.
This talk will present a brief survey of known kaḷarippayaṟṟ˘ texts and discuss the methodologies I have evolved to collect and analyse discrete sections of otherwise closely- guarded texts from the CVN lineage that is the chief focus of my research. I will discuss these and their working translations, which are still evolving as part of my PhD project. This textual analysis has been guided by Dr. SAS Sarma at l'École française d'Extrême-Orient at Pondicherry.
My PhD is at the Open University in the UK, exploring the relationship between practice and textual traditions in kaḷarippayaṟṟ˘, funded by the UK Arts and Humanities Research Council’s Open-Oxford-Cambridge Doctoral Training Partnership. This interdisciplinary research encompasses ethnography, drawing on a relationship since 2002 with CVN Kalari in Thiruvananthapuram, and the study of manuscripts in Malayalam and Sanskrit. My background is in dance and somatic practices, where my work investigates the confluence of my praxes of postmodern dance, martial arts and yoga.

Dr Singh will make a 30-minute presentation on the discussions and reflections on vijñāna in the Hindi-language science monthly that she studies, Vigyan. She requests that we combine this presentation with a group discussion on the readings above. Dr Singh says: "In choosing programmatic work in the global history of science (Elshakry) with South Asian reflections on knowledge categories (Pollock, Menon), I'm hoping we can all together think through the problem presented by several cognates of "science" across premodern and modern South Asia. In addition, I'm hoping that the empirical evidence I will provide for one such knowledge category can serve as a case study for our discussion."

Varier Ayurveda College (URL) Title: Influence of the Suśrutasaṃhitā on the Structure and Contents of the Aṣṭāṅgasaṅgraha: Insights from the Ongoing Critical Edition of Five Selected Chapters from the Sūtrasthāna of the Aṣṭāṅgasaṅgraha Abstract: The Aṣṭāṅgasaṅgraha (AS) and the Aṣṭāṅgahṛdaya (AHS), two texts ascribed to Vāgbhaṭa mark the conclusion of an important period in the history of Indian medicine known as the period of the text compendia (saṃhitākāla). While drawing influence and materials from the earlier Carakasaṃhitā (CS) and the Suśrutasaṃhitā (SS), the AS and AHS show remarkable ingenuity in restructuring and editing text materials. The similarity in the structure of the sections (sthānas) in SS and AS often leads scholars to assume that the structure and design of AS is predominantly inspired by the SS. Based on an ongoing critical edition of the AS, this talk tries to address this issue along with a host of other issues regarding the influence of the SS on the structure and contents of the AS.

Speaker: Eric Gurevitch, PhD candidate South Asian Languages and Civilizations and Committee on Conceptual and Historical Studies of Science University of Chicago
Title: Diseases of the eye: Debating the physiology of vision across medicine and philosophy in medieval India Abstract: Philosophy mattered in medieval India. Philosophers were employed in royal courts and mediated scholarly life and disputes across sectarian and disciplinary lines. At the heart of philosophic disputes were questions of perception, and these often revolved around the physiology of vision. This presentation examines how philosophers made appeals to medical practices and how medicine was invoked in new contexts. It focuses on two 11th-century scholars who argued for the inadequacy of the standard account of visual extramission as given in philosophic, medical, and literary texts written in Sanskrit. These scholars looked back to 500 years of philosophic disputes as well as to medical practices and argued that the eyeball worked in a very different manner than was often assumed. The presentation aims to tell a more plural history of perception in pre-colonial South Asia and does so by moving across scholarly genres and disciplines. The presentation will be aimed at both generalist and specialist audiences and all are welcomed to join in and participate.

Speaker: Dr Cristina Pecchia, Austrian Academy of Sciences (URL) Title: Gangadhar Ray Kaviraj and the Carakasaṃhitā. Abstract: Gangadhar Ray (1798–1885) was the editor of the first printed edition of (part of) the Carakasaṃhitā, that appeared in 1868 in Calcutta and seemingly became the basis of several successive editions of the text. His edition of the Carakasaṃhitā and commentary on it, the Jalpakalpataru, can be counted among the important achievements of his scholarly life. The presentation aims to analyse Gangadhar’s philological activity concerning the Carakasaṃhitā, that also represents a piece of traditional scholarship from 19th century South Asia. In the absence of documentary evidence, we will mainly be examining the text of the Carakasaṃhitā transmitted in manuscripts and printed books associated with Gangadhar’s name. We will explore the context made up of texts – in Ganeri’s words the “intertextual context” – that actors involved in this transmission inhabited, we will look at what variants can reveal about philological practice, and reflect on the larger topic of philology in colonial South Asia as a chapter of Indian intellectual history.

Speaker: Dr Philipp A. Maas, Associate Professor, Martin Luther University Halle-Wittenberg (URL) Title: The cultural identity and religious orientation of early classical Ayurveda
Abstract More than once in the history of Indological research, scholarly opinions regarding the original cultural milieu and religious orientation of Ayurveda have altered. Initially, scholars regarded Ayurveda as an off-shoot of Vedic Brahmanism. In the 90s of the last century, Ken Zysk strongly challenged this view by arguing that Ayurveda’s apparent affiliation to Vedic Brahmanism merely reflects the endeavor of Ayurvedic physicians to create acceptance in a society committed to Vedic norms and values. According to Zysk, ayurvedic medicine was initially developed in Buddhist and cognate ascetic milieus. In 2007, Johannes Bronkhorst advanced Zysk’s line of argument. Bronkhorst hypothesized that the rational-empirical medicine of Ayurveda was a distinctive feature of the culture of Greater Magadha, a region that he identified as Ayurveda’s cultural homeland. In the present reading session, we reconsider Bronkhorst’s hypothesis based on selected passages from the earliest preserved medical Sanskrit compendia, the Carakasaṃhitā (CS) which distinctively reflect physicians’ religious orientations and cultural identity. The session starts with an analysis of the two origin myths of Ayurveda and Rasāyana in CS Sūtrasthāna 1.13–40 and Cikitsāsthāna 1.4.3f. Both passages programmatically position Ayurveda in its contemporary cultural and religious environment by integrating religious ideas that Bronkhorst identified as characteristics of Vedic Brahmanism and the religion of Greater Magadha. Taking into consideration additional textual materials from the CS and Strabo’s Geography, I suggest, however, that the cultural and religious hybridity of the CS does not exclusively result from the Brahminization of medical knowledge of Greater Magadha. Various medical currents of thought merged in the ayurvedic school of Punarvāsu Ātreya to form a specific religious and social group with a distinct identity and worldview. This group mythologically located its region of origin in the mountains of the Himalayas rather than in the cities of greater Magadha. Text passages:

And [they say that] some [philosophers] are called mountain-dwelling, others naked, and others urban and neighbouring, and [the] mountain-dwelling [philosophers] use (i.e., wear) hides of deer and have leather pouches, full of roots and drugs, claiming to practice medicine with sorcery, spells, and amulets."
