Mbh 13.57.3a

"'Bhishma said, "Hear what I say unto thee. It is exceedingly wonderful, and constitutes a great mystery. The topic is the object that creatures obtain after death as the rewards of particular acts or courses of conduct they follow. One attains to Heaven by penances. By penances one attains to fame. By penances, O puissant king, one attains to length of life and all articles of enjoyment. By penances one attains to knowledge, to science, to health and freedom from disease, beauty of person, prosperity, and blessedness, O chief of Bharata's race. By penances one attains to wealth. By observing the vow of taciturnity one succeeds in bringing the whole world under one's sway. By making gifts one acquires all kinds of enjoyable articles. By observing the right of Diksha one acquires birth in a good and high family. Those that spend their lives subsisting only upon fruits and roots (and avoiding cooked food) succeed in obtaining kingdom and sovereignty. Those that live upon the leaves of plants and trees as their food succeed in attaining to heaven. One that subsists upon water only attains to heaven. By making gifts one simply increases one's wealth. By serving with reverence one's preceptor one acquires learning. By performing Sraddhas every day in honour of one's Pitris (manes), one acquires a large number of children. By observing Diksha upon potherbs and vegetables, one acquires a large number of kine. Those that subsist upon grass and straw succeed in attaining to heaven. By bathing thrice every day with the necessary rites one acquires a large number of spouses. By drinking water alone one acquires residence in the regions of Prajapati. The Brahmana, who bathes every day and recites sacred Mantras in the twilights, becomes possessed of the status of Daksha himself. By worshipping the deities in a wilderness or desert, one acquires a kingdom or sovereignty, and by observing the vow of casting off the body by a long fast, one ascends to Heaven.
