The Essence of Tibetan Buddhism by Lama Thubten Yeshe consists of three teachings. The first one, The Three Principal Aspects of the Path, was given in France in 1982, during an sponsored tour of Europe by His Holiness the Dalai Lama. Just before His Holiness’s scheduled teachings at Institut Vajra Yogini, His Holiness manifested illness and asked Lama Yeshe to fill in for a couple of days to baby-sit the audience, as Lama put it. This two-part teaching on three principal aspects of the path is the result. The second teaching, an Introduction to Tantra, also in two parts, was given at Grizzly Lodge, California, in 1980. It comprises the first two lectures of a commentary on the Chenrezig yoga method taught by Lama at the request of Vajrapani Institute,
