Lama Yeshe
Lama Thubten Yeshe was a monastic teacher of Tibetan Buddhism most closely associated with the Gelug school of the Dalai Lamas. He established the Foundation for the Preservation of the Mahayana Tradition (FPMT), and was succeeded in leadership of that organization by his heart-disciple Lama Thubten Zopa in 1984.
“There is no miserable place waiting for you, no hell realm, sitting and waiting like Alaska—waiting to turn you into ice cream. But whatever you call it—hell or the suffering realms—it is something that you enter by creating a world of neurotic fantasy and believing it to be real. It sounds simple, but that's exactly what happens.”
