Throughout its history, members of the Sakyapa tradition who have been considered masters have been those who brought the aspects of study and practice into a proper balance. Although these masters taught and practiced the various teachings found in both the Mahayana sutras and the tantras of various lineages, the heart of the Sakyapa tradition—that which makes it a distinct entity and which has sustained its vitality over the centuries—is the teaching known as the “Path Including Its Result” (Lam Dre).
From Virupa, this teaching was transmitted through four successive Indian masters before arriving in Tibet, where the great translator Domi Lotsawa Sakya Yeshe (’Brog.mi Lo.tsa.ba Sha.kya Ye.shes), 993–1077, rendered it into the Tibetan language. However, it was not until the time of Sachen Kunga Nyingpo that the written commentarial tradition began to grow around the Lam Dre, the “Path Including Its Result” teaching. Sachen himself wrote eleven commentaries on various aspects of the teaching.
