There cannot be anything more serious than spiritual attainment. If a person takes that lightly he does not know what he is doing. It is better not to go into these things at all, rather than go and come back empty-handed. To come back disappointed from the spiritual path before reaching the final goal is the worst possible thing. To go bankrupt does not matter. One can pick up again what one has lost in the world. But the man who has embarked on the spiritual path and has turned back is to be pitied. It is the greatest loss and can never be repaired.
