Bhagavad Gita
benefits one reaps from doing Dāna
If we give annadāna, we satisfy a person for three hours. After three hours, again he needs food. If we give vidyādāna, education or knowledge, he will have food for himself for one life. If we give education, he can earn food for himself. He will make money and buy food for himself. If we give jñānadāna, we will satisfy that person birth after birth! He will never fall into depression or the ocean of material world, birth after birth.
