 Some light is shed on this work by a contemporaneous Buddhist work, the Vaidalya-prakaraṇa (Tract on pulverization), attributed to Nāgārjuna. It is organized around the key terms listed in the first aphorism of the Nyāya-sūtra (NS 1.1.1). However, it does not explain the terms nor does it illustrate them. Instead, it sets out for each term arguments intended to show its incoherence. It is therefore rich in arguments, most of which are analogical. The author also judges a number of counter arguments as fallacious, pointing out either that they are circular or that they lead to an infinite regress.
