Study notes

The foundation year's philosophy paper. It answers the question a first-year student rarely asks out loud: on what grounds does Ayurveda claim to know anything? The answer is pramana, and the framework is borrowed and adapted from the darshanas.

Padartha — the categories

• Vaisheshika gives six padartha: Dravya, Guna, Karma, Samanya, Vishesha, Samavaya. Later works add Abhava, making seven.
• Charaka's own list in Sutrasthana chapter 1 gives six: Samanya, Vishesha, Guna, Dravya, Karma, Samavaya — note the ORDER differs from Vaisheshika, and that is examinable.
• Dravya is the substrate; guna and karma inhere in it. Samanya increases, vishesha decreases — the single most quoted line in the subject.

Dravya, Guna, Karma

• Nine dravya: prithvi, ap, tejas, vayu, akasha, kala, dik, atma, manas.
• Guna: twenty-four in Vaisheshika; forty-one in Ayurveda, made up of twenty gurvadi, ten paradi, six adhyatmika and five vishesha (the indriyartha). State which scheme you are using.
• Karma: five — utkshepana, apakshepana, akunchana, prasarana, gamana.

Pramana — how anything is known

• Charaka accepts four: Aptopadesha (authoritative testimony), Pratyaksha (perception), Anumana (inference), Yukti (reasoning from multiple causes).
• Yukti is Ayurveda's own addition and is worth explaining carefully — Nyaya does not have it.
• Nyaya accepts four: pratyaksha, anumana, upamana, shabda. The difference between the two lists is a standard question.
• Pariksha in clinical use: trividha, shadvidha, ashtavidha, dashavidha.

The darshanas

• Nyaya (logic), Vaisheshika (categories and atomism), Sankhya (twenty-five tattva), Yoga (Patanjali), Mimamsa, Vedanta.
• Ayurveda draws most heavily on Sankhya for its cosmology and on Nyaya-Vaisheshika for its epistemology and categories.
• Sankhya's twenty-five tattva and the order of evolution from Purusha and Prakriti is examinable as a sequence.

Ayurveda Itihasa

• Divine origin account: Brahma to Daksha Prajapati to the Ashwini Kumaras to Indra, then to Bharadwaja/Atreya and to Dhanwantari.
• Brihattrayi: Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya. Laghutrayi: Madhava Nidana, Sharangadhara Samhita, Bhavaprakasha.
• Charaka Samhita: eight sthana, 120 chapters. Redacted by Charaka and later completed by Dridhabala, who wrote seventeen chapters of Chikitsasthana and the whole of Kalpa and Siddhi sthana — a standard question.
• Sushruta Samhita: six sthana, 186 chapters including Uttaratantra. Commentators: Chakrapani on Charaka, Dalhana on Sushruta, Arunadatta and Hemadri on Ashtanga Hridaya.
• Modern period: the establishment of colleges, CCIM and its replacement by NCISM, and the Ministry of Ayush.

Samanya and Vishesha

• Samanya is likeness and causes increase; Vishesha is difference and causes decrease. This is the single operating principle of Ayurvedic therapy — mamsa increases mamsa, and an opposite quality reduces it.
• Three types of samanya: Dravya samanya, Guna samanya, Karma samanya. Vishesha likewise.
• By extent: Para (the widest, sattā), Apara (the narrowest) and Paraapara (intermediate).
• Practical use: in a wasted patient you give substances like the tissue you wish to build; in excess you give the opposite. Every chikitsa decision reduces to this.

Samavaya and Abhava

• Samavaya is the inseparable, eternal relation between a substance and its qualities. Guna cannot exist without dravya.
• Contrast with Samyoga, which is separable conjunction — two things temporarily joined.
• Abhava is non-existence, of four kinds: Pragabhava (prior), Pradhwamsabhava (posterior), Anyonyabhava (mutual), Atyantabhava (absolute).
• Examinable distinction: samavaya is nitya and asamavayi; samyoga is anitya.

Panchamahabhuta and Tridosha siddhanta

• The five mahabhuta — Prithvi, Ap, Tejas, Vayu, Akasha — each with its own guna and its own sense.
• Panchikarana: the process by which the subtle elements combine to produce the gross ones.
• Dosha from bhuta: Vata from vayu and akasha; Pitta from tejas (with a little ap); Kapha from prithvi and ap.
• Rasa from bhuta: madhura from prithvi+ap, amla from prithvi+tejas, lavana from ap+tejas, katu from vayu+tejas, tikta from vayu+akasha, kashaya from vayu+prithvi. This mapping is asked directly.

Pramana — the means of valid knowledge

• Aptopadesha: the testimony of a reliable authority. Who counts as apta is itself defined — free from raga, dwesha and moha.
• Pratyaksha: direct perception through the five senses and the mind. Its limits are stated in the texts, which is unusual and worth quoting.
• Anumana: inference, based on a known invariable relation. Three times — past, present, future.
• Yukti: reasoning from the conjunction of multiple causes producing an effect. Charaka's own addition, and some commentators dispute whether it is a separate pramana at all — say so.

The Brihattrayi and Laghutrayi

• Brihattrayi: Charaka Samhita (Kayachikitsa emphasis), Sushruta Samhita (Shalya emphasis), Ashtanga Hridaya of Vagbhata (a synthesis).
• Laghutrayi: Madhava Nidana (diagnosis), Sharangadhara Samhita (pharmacy and pulse), Bhavaprakasha (materia medica and the nighantu).
• Ashtanga Sangraha is Vagbhata's longer prose work; Ashtanga Hridaya the condensed verse one.
• Nighantu literature: Dhanwantari, Raja, Kaiyadeva, Bhavaprakasha, Madanapala, Shodhala — worth knowing which century each belongs to.

Contemporary status and regulation

• CCIM was constituted under the Indian Medicine Central Council Act 1970 and replaced by NCISM under the NCISM Act 2020.
• The Ministry of Ayush was created in 2014, having previously been a department.
• Ayurveda's legal status differs sharply by country: a licensed medical profession in India, Nepal and Sri Lanka; not a licensed profession in the USA or UK; recognised within the public health system in Brazil.
• WHO Traditional Medicine Strategy and the ICD-11 traditional medicine chapter are the international reference points.

Ashtanga Ayurveda and the karya-karana vada

• ASHTANGA AYURVEDA, the eight branches — a certain question and one that is often missed: Kayachikitsa, Balaroga (Kaumarabhritya), Grahachikitsa (Bhutavidya), Urdhwanga (Shalakya), Shalya, Damshtra (Agada), Jara (Rasayana) and Vrisha (Vajikarana).
• KARYA-KARANA VADA — the theories of causation, and which darshana holds which: SATKARYAVADA (Sankhya) says the effect pre-exists in the cause. ASATKARYAVADA or ARAMBHAVADA (Nyaya-Vaisheshika) says it does not. PARINAMAVADA is the Sankhya position that the cause transforms into the effect.
• Ayurveda follows both: arambhavada for the panchabhautika composition of dravya, and parinamavada for digestion and dhatu formation. It is not doctrinaire and says so.
• PILUPAKA (Vaisheshika) and PITHARAPAKA (Sankhya) are the two theories of how paka happens — whether the change occurs in the atoms individually or in the whole mass. Charaka's digestion follows pitharapaka.
• Nyaya has SIXTEEN padartha, of which pramana, prameya and the debate terms matter most to a vaidya.

Vada-marga — the forty-four terms of debate

• Charaka Vimana 8 gives forty-four vada-marga: the vocabulary of a scholarly debate, and a whole examinable unit that is easy to skip.
• The three kinds of exchange: VADA (discussion to find truth), JALPA (debate to win) and VITANDA (mere refutation with no position of one's own). A vaidya is taught to engage in vada and to recognise the other two.
• SANDHAYA SAMBHASHA is friendly discussion; VIGRIHYA SAMBHASHA is hostile. Charaka says whom to debate and whom not to, and in front of whom.
• The terms include pratijna (proposition), sthapana (establishment), pratisthapana (counter-establishment), hetu, drishtanta, upanaya, nigamana — which is the five-membered Nyaya syllogism inside Charaka.
• Chala, jati and nigrahasthana are the ways an argument is defeated — quibbling, futile rejoinder, and the point of defeat. Nigrahasthana is where a debate formally ends.

Where the texts disagree

• Vaisheshika gives six padartha; later Vaisheshikas add abhava as a seventh. Charaka's six karana padartha are not identical to either list.
• Ayurveda accepts four pramana; Nyaya accepts four but not the same four, and yukti is Charaka's own.
• Whether Ayurveda follows Samkhya or Vaisheshika more closely is a standing question, and the honest answer is that it borrows from both.

Commonly confused

• Samanya (increases) and Vishesha (decreases).
• Samavaya (inherent, inseparable) and Samyoga (conjoined, separable).
• Gurvadi guna (twenty, in substances) and Paradi guna (ten, in treatment).
• Pratyaksha, anumana, aptopadesha and yukti - four pramana, and yukti is the one peculiar to Ayurveda.
