Service is best built on the strong foundation of Tath-Thwam-Asi.  (That and This are the same) - there is no other. There is only One.  Kites fly high, but all are lifted and kept high by the same air, the same wind. The kites have no separate will. The pots of water in which the Sun is reflected may be many, but the Sun is One. When another is poor, you cannot be rich. When another is in distress, you cannot have joy. The same current runs through and activates all. All help you give is therefore help given to yourself, all service is to the Self alone. 

- Divine Discourse, March 7, 1980.

Love all, Serve All. Help Ever, Hurt Never- Baba
