"At the beginning, mankind and the obligation of selfless service were created together. Through selfless service, you will always be fruitful and find the fulfillment of your desires: this is the promise of the Creator... Every selfless act, Arjuna, is born from Brahman, the eternal, infinite Godhead. Brahman is present in every act of service. All life turns on this law O Arjuna. Those who violate it, indulging the senses for their own pleasure and ignoring the needs of others, have wasted their life. But those who realize the 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."
