"Every selfless act, Arjuna, is born from the eternal, infinite Godhead. God 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 the God within are always satisfied. Having found the source of joy and fulfillment, they no longer seek happiness from the external world...Strive constantly to serve the welfare of the world; by devotion to selfless work one attains the supreme goal in life. Do your work with the welfare of others always in mind. It was by such work that Janaka attained perfection; others, too, have followed this path. The ignorant work for their own profit, Arjuna; the wise work for the welfare of the world, without thought to themselves." (Bhagavad Gita 3:10-26)
"Neither in heaven nor in Brahma's world do men experience such joy as arises from conferring bliss on suffering creatures. If, while I am present, torment does not hurt these men, here then will I remain, firm as a mountain...As long as these beings are in sore suffering, I will not go. From my presence the denizens of hell grow happy. Fie on the sickly protection-begging life of that man who shows no favor to one distressed, even though he be a resolute foe! Sacrifices, gifts, austerities do not work for the welfare of him who has no thought for the succor of the distressed....To grant deliverance to these men excels, I consider, the joy of heaven. If many sufferers shall obtain happiness while only I undergo pain, shall I not in truth embrace it?" (Markandeya Purana 13-15)
"The gods have not ordained that humans die of hunger; even to the well-fed man death comes in many shapes. The wealth of the generous man never wastes away, but the miser has none to console him. He who, possessed of food, hardens his heart against the weak man, hungry and suffering, who comes to him for help, though of old he helped him--surely he finds none to console him. He is liberal who gives to anyone who asks for alms, to the homeless, distressed man who seeks food; success comes to him in the challenge of battle, and for future conflicts he makes an ally. He is no friend who does not give to a friend, to a comrade who comes imploring for food; let him leave such a man--his is not a home--and rather seek a stranger who brings him comfort. Let the rich man satisfy one who seeks help; and let him look upon the long view: For wealth revolves like the wheels of a chariot, coming now to one, now to another. In vain does the mean man acquire food; it is--I speak the truth--verily his death; he who does not cherish a comrade or a friend, who eats all alone, is all sin." (Rig Veda 10:117.1-6)
"Rantideva, who, though himself hungry, was in the habit of giving away his wealth as it came, while trusting in God to provide his needs. Even in time of famine, Rantideva continued his generosity though his family was reduced to poverty. For forty-eight days he and his family were starving; a little liquid, and that enough for only one, was all that remained. As he was about to drink it, an outcaste came begging for water. Rantideva was moved at the sight and said, "I do not desire from God the great state attended by divine powers or even deliverance from rebirth. Establishing myself in the hearts of all beings, I take on myself their suffering so that they may be rid of their misery." So saying, the compassionate king gave that little liquid to the outcaste, though he himself was dying of thirst." (Srimad Bhagavatam 9)
"No one who does good deeds will ever come to a bad end, either here or in the world to come. When such people die, they go to other realms where the righteous live." (Bhagavad Gita 6:40-41)
"He who gives liberally goes straight to the gods; on the high ridge of heaven he stands exalted." (Rig Veda 1:125.5)
"Giving simply because it is right to give, without thought of return, at a proper time, in proper circumstances, and to a worthy person, is enlightened giving." (Bhagavad Gita 17:20)
