Je Tsognkhapa (Tib.: tsong kha pa, ཙོང་ཁ་པ། "The Man from Onion Valley") was a monk of the Sakya tradition of Tibetan Buddhism whose activities led to the formation of the Geluk school, though he never announced the establishment of a new monastic order himself. He is also known by his ordained name Lobsang Drakpa (blo bzang grags pa) or simply as Je Rinpoche (rje rin po che).
I am not the fan of this translation in particular, it seems too technical and dry for the most part and I had hard time staying awake and had to re-read parts of the chapters multiple times to reinforce understanding. I am not completely brand new to the topic and this edition is not my favorite. I prefer "Deity Yoga" and "Yoga Tantra" instead.
