Dharmarāja Adhvarin’s Vedānta Paribhāṣā is a well-known introduction to Advaita Vedānta, targeted to beginners who are already trained in Navya Nyāya. According to Dasgupta, the VP is so heavily indebted to Rāmādvaya’s Vedānta Kaumudī, which was composed in the middle of the 14th century and is today almost forgotten, that the VP’s “claim to originality vanishes”. The VK was, however, only edited in 1955 and then again in 1973. In the light of this improved textual basis, what is our judgement (...) about Dasgupta’s hypercritical statement? Did actually the VP ever claim to be original? Was this originality somehow superimposed on the VP later? Is the VP really so much indebted to the VK? This paper aims at comparatively analysing the textual background of these questions. I will start from the analysis of one Advaita’s epistemological tenet, namely the valid knowledge, in the VK and then compare it to the corresponding parts in the VP. (shrink)
