half-remembered term, finally found again

Bangsaeng! (방생, 放生)

The term bangsaeng is associated with a Buddhist ceremony involving the periodic (and often symbolic) release of captured joongsaeng (creatures, sentient beings—usually fish and birds).  For the longest time, I would rack my brains in an effort to remember this term, and now that I've remembered it, I'm noting it here for future reference:  if I don't note the term here, I'm very likely to forget it again.
