Engage yourselves in selfless service. The reward for it will come of its own accord. Do not have any doubts on this score. Whatever you undertake, do it with all your heart and to your full satisfaction. That satisfaction is all the reward and recompense that you will need. It will confer great strength on you. This is the virtue that you have to cultivate. Acquire this true wealth. Without goodness, all other riches are of no avail.

-Divine Discourse, 11th March 1994.

See Good, Be Good and Do Good.  This is the way to God. - Baba
