Commentary on the Nyāyapraveśa, a treatise on Buddhist logic by Śaṅkarasvāmin (active 6th century) which itself introduces Dignaga's root text, the Nyāyamukha. Professor Sempa Dorjee offers an exegesis of difficult points based on a rare Sanskrit manuscript held by a library in South India and in consultation with Tibetan translations in the Narthang, Derge, Cone and Taishō canons.
