The authority of Jain medicine

The editor says the Jain āgama is authoritative because it is taught by the Omniscient: the gaṇadharas divide the divine voice into the twelve aṅgas, the twelfth of which has fourteen pūrvas, one being the Prāṇāvāya, defined as the scripture that sets out the eight-limbed Ayurveda, the action of the elements, poisonous creatures and their treatment, and the division of prāṇa and apāna. Quoting chapter 25, verse 54, he says Ugrādityācārya composed the Kalyāṇakāraka by condensing that Ardhamāgadhī scripture into Sanskrit, so the work belongs to the twelve-limbed canon and is fully authoritative.
