Ugraditya's teacher

The author says he learned the canon, the doshas, the severe diseases they cause and their treatment, drawn from the Pranavada, by the grace of Shrinandi Acharya, whom the commentary names as Ugraditya's guru; a footnote places the Pranavada Purva in the twelfth limb (Drishtivada) of the Jain canon as the root text of eight-limbed Ayurveda.
