Mbh 12.66.2a

"'Bhishma said, "O Yudhishthira of mighty arms, all the duties that are practised in this world by the righteous are known to thee as they are known to me. O foremost of virtuous persons, listen now to me about what thou askest, viz. the merit (that a king acquires) in consequence of the duties practised by others leading other modes of life.[206] All the merits, O son of Kunti, that belong to persons practising the duties of the four modes of life, attach, O foremost of men, to righteous kings. A king who is not governed by lust and hate, who rules with the aid of the science of chastisement, and who looks equally on all creatures, O Yudhishthira, attains to the object of the Bhaikshya mode of life.[207] That king who is possessed of knowledge, who makes gifts to deserving persons on proper occasions, who knows how to favour and punish, who conducts himself in all things according to the injunctions of the scriptures, and who has tranquillity of soul, attains to the object of the Garhasthya mode of life. That king who always worships those that are deserving of worship by giving them their due, completely attains, O son of Kunti, to the object of the Bhaikshya mode of life. That king, O Yudhishthira, who rescues from distress, to the best of his power, his kinsmen and relatives and friends, attains to the object of the Vanaprastha mode of life. That king who on every occasion honours those that are foremost among men and those that are foremost among Yatis, attains, O son of Kunti, to the object of the Vanaprastha mode of life. That king, O Partha, who daily makes offerings unto the Pitris and large offerings unto all living creatures including men, attains to the object of the same mode of life. That king, O tiger among men, who grinds the kingdoms of others for protecting the righteous, attains to the object of the same mode of life.
