Knowledge generation in Āyurveda has followed mainly four types of siddhānta (theory) viz. 1. śarvatantra siddhānta (the theory which is accepted by all śāstrā-s), 2. pratitantra siddhānta (the theories not in any other śāstrā-s:), 3. adhikaraa siddhānta (from the related topics and theories) and 4. abhyupagama siddhānta (unproven and not fully tested theories). These siddhānta-s were debated among groups of scientists and students of various schools of thought. The methods of such discourses are guided by 44 rules of logic, ‘vādamārga’ (CS. Vi.8.26) to justify propositions. The Āyurvedic texts are formulated based on the 32 criteria (Suśruta Sahita; SS.Utta.65) and 36 criteria by Caraka (CS.Si.43) known as tantra-yukti in order to ensure rigour. Āyurveda considers knowledge of whole cannot be obtained by knowing its parts. Key words: Āyurveda, Darśana, Knowledge, Logic, Tantrayukti, Vādamārga. 1. INTRODUCTION 2. GENERATION OF AYURVEDIC KNOWLEDGE Āyurvedic knowledge has a long history Caraka says that the entire world is the in the country, most part of which is lost due to its teacher to the intelligent and foe to the being part of old oral tradition. Some of the oral unintelligent. Knowing this well, with proper traditions of ancient times, the Vedic brāhmaic attention, one should listen even to an unfriendly and the heterodox, have survived, thanks to their person. ‘Purucōyam lōkasammita’: ‘Human being is a microcosm of the physical and biological sacred nature. What we know as the history of world’ (CS. Vi.8.14). All entities in the universe yurveda is mainly based on sahitā-s mainly of Ā are there in the person and vice versa.

KNOWLEDGE GENERATION IN ĀYURVEDA: METHODOLOGICAL ASPECTS 49 sets of information are strung out as if along a In Āyurveda the basic knowledge is the thread. This is like a thread which holds together knowledge about the knowable object, padārtha beads or flowers in a garland. The knowledge thus vijñāna. The knowledge of the material, its preserved is in a condensed form, very precise and practical context and the observation of results are free of repetitions, enabling its remembrance and fundamental to the generation of Āyurvedic retrieval on demand relatively easy. Subsequently knowledge. In Āyurveda, padārtha vijñāna is all this was codified and systematised in the form extended into a holistic understanding with of written texts, namely sahitā-s (the theoretical foundations and logical arguments compendia). Both the modes had followed the emphasizing practical relevance. Sahitā-s of poetic genre for the organisation of knowledge. Āyurveda hold this knowledge as eternal (śāśvata) Āyurvedic texts start with a chapter known as and without beginning (anādi) because it deals sūtra-sthāna which explains the fundamental with properties of entities of a universal nature features and principles of the knowledge they (svabhāva sasiddha lakcaatvāt ) which has embody by way of the philosophy, logic and permanent (bhāva svabhāva nityatvāt ) characters concepts. The systematised texts of the sahitā (CS. 30: 27). tradition also followed the same style of precision. – – Naturally at a later stage this necessitated 3.
