A quote from Tracts of the Sun:
We have bad news for you all. You've just fallen from an incredible height into a bottomless crevasse. However — that's also the great news. It's bottomless, so you're falling into space. Happy landings.
–Ngak'chang Rinpoche and Khandro Dechen
Cheerful and — unconventional? "Happy landings." One could object — no crevasse is really bottomless. But that's just such a point this makes? If it were really bottomless — no landings.
