Drokmi Lotsāwa’s personal name is Śākya Yeshé. He was the first Tibetan lama to have received the Lamdré teachings. He gave Könchok Gyalpo many teachings, especially the Hevajra Tantra, but not the Lamdré teaching. Drokmi Lotsāwa did not give the two different types of teachings to the same person. Lamdré teaching is a pith instruction. So Drokmi Lotsāwa did not give pith instructions to those who received tantras from him. If students received teaching on tantra from him, then he did not give them pith instruction. He introduced his best disciples to the pith instruction. Lama Sakyapa Kunga Nyingpo received his Lamdré teaching from Drokmi Lotsāwa’s disciple, Shangton Chobar. In this way, Lamdré is the main teaching of the Sakyapa. Lamdré is the path and result—it has everything—the sūtrayāna path, which is the preliminary part, and the Vajrayāna path that is the main part; it is a complete teaching starting from refuge up to enlightenment; how one person attains enlightenment.
