Yoga in the Hindu Schools

Suicide is a violent act not against the self but expressed outwardly to try to destroy something. Reincarnate doctrines of reincarnation and like afterworld leanness generally are really sort of important. If you know everyone in your cult kills themselves it's very unlikely other people will join the cult so they need some way for that not to happen. You don't want to do any damage that doesn't absolve you from suffering because then you're dead which is an undefinable state.
