A Survey of the Paths of Tibetan Buddhism by Dalai Lama
From the intro:
“In giving an overview of the Buddhadharma, as practised by the Tibetans, I generally point out that the Buddhism we practice is an integrated form comprising teachings of the low, Bodhisattva and Tantric vehicles, including such paths as the Great Seal. Because quite a number of people have already received initiations, teachings and so on, they might find it helpful to have an explanation of the complete framework.
People of other religious traditions, who have an interest in Buddhism and who find such features of Buddhist practice as the meditiative techniques for developing love and compassion attractive, could also benefit by incorporating them into their own tradition and practice.” Dalai Lama 1988.
by Tenzin Gyatso, 14th Dalai Lama of Tibet.
