Pramāṇavārttikavṛtti by Ravigupta

The title is transmitted in PVV (R)-t Peking 5726, 137a8 as "pramāṇavārtikasya vṛtti", so that for PVV (R)-t A Peking 5722, the name "vṛtti" is also to be assumed. The work is a direct commentary on the Pramāṇavārttika, on the second (pramāṇasiddhi) and third (pratyakṣa) chapters. The two chapters are separated into different volumes in the bstan 'gyur, and completely separated in Peking.
