The Sūtra on the Threefold Training
From Rigpa Wiki
The Sūtra on the Threefold Training (Skt. Śikṣātrayasūtra, Tib. བསླབ་པ་གསུམ་གྱི་མདོ་, Wyl. bslab pa gsum gyi mdo) is found in the General Sūtra (mdo sde) section of the Tibetan Kangyur (Toh 282).
This very brief sūtra introduces the "three trainings": discipline, meditative concentration, and wisdom. The buddha teaches that training progressively in these three constitutes the gradual path to awakening.
