"Every selfless act, Arjuna, is born from Brahman, the eternal, infinite Godhead. He is present in every act of service. All life turns on this law, O Arjuna. Whoever violates it, indulging his senses for his own pleasure and ignoring the needs of others, has wasted his life. But those who realize he Self are always satisfied. Having found the source of joy and fulfillment, they no longer seek happiness from the external world. They have nothing to gain or lose by any action; neither people nor things can affect their security. Strive constantly to serve the welfare of the world; by devotion to selfless work one attains the supreme goal of life. Do your work with the welfare of others always in mind."
