The Indian Buddhist scholar Ratnakarasanti, a master of both tantric (mantranaya) and non-tantric (paramitanaya) Mahayana Buddhism, wrote at least four works related to the Hevajratantra and the system of practice associated therewith. Probably the most important of them is a lengthy commentary, called Muktavali, on the tantra itself, a work in which Ratnakarasanti explicitly attempts to show that tantric practice of the kind taught in the Hevajratantra does not conflict with, but rather is in perfect accordance with, the basic teachings of (nontantric) Buddhism. This commentary fortunately survives in Sanskrit manuscripts as well as in a not very reliable Tibetan translation ; an edition and translation of its opening verses has recently been published (ISAACSON 2001), and a complete critical edition is under preparation by the present author.
