This has been on my wish list for a while now. Published in 2006, this is the first English translation of Dolpopa Sherab Gyaltsen’s masterpiece titled Mountain Doctrine wherein he gives precise teachings on the rangtong (self-emptiness) and zhentong (other-emptiness) views. I am currently re-reading The Buddha from Dolpo by Cyrus Stearns, which is excellent–both in offering a basic biography of Dolpopa as well as providing many of his arguments regarding Buddhanature and other teachings. Dolpopa was also a master of Kalachakra tantra, and is recognized as such even to this day by many of the Vajrayana lineages (not just the Jonang).
For those who are interested in Buddhadharma but have never heard about Dolpopa, I recommend checking him out (probably starting with The Buddha from Dolpo). Hopefully we will see more from Dolpopa in English, as his collected works are gaining attention in academia.
