It doesn’t teach dying to one’s self, literally suffering the pain of death to the world and its value.
This is a such suicide ,which is symbolic act.It casts off the

psychological posture that you happen to be in at the time.So that you come into a better one.
you die to your current life in order to come to another of some kind.
As Carl Jung says, you’d better not get caught in a symbolic situation.you don’t have to die, really,physically.
All you have to do is die spiritually and be reborn to a larger way of living.
In marriage or in any military or any mission, people wearing new dresses,that are symbolic of psychological transformation.
your psychological center is changed now.
you are acting not for your own interest but for the relationship or a community etc.
