Kamalasila is one of those distinguished acharyas who went to Tibet from India, stayed there and wrote scholarly treatises on Buddha dharma. The present work is the first-ever English rendering from original Sanskrit, suggested by the Dalai Lama.
The original text is interesting but this is a hard translation to read. I feel that the translator left too many sanskrit terms untranslated so it's hard to get through. I find myself needing to look up words page after page.
