In this interesting article, Adele Hulse explains where the Foundation for the Mahayana Tradition (FPMT) received its name. Lama Yeshe was noted as saying:
I want to preserve the Mahayana teachings. If you can’t get the name right, you don’t know what I’m doing.
Also in this article is an interesting story on how Mahakala became the official Dharma protector of the FPMT, and what the meaning of “empowerment” or “initiation” is in Tibetan Buddhism.
