Mbh 12.61.1b

With careful attention he should accomplish all the duties of this mode of life that is applauded by ascetics and that is extremely difficult to go through (without transgressions). He should be satisfied with his own wedded wife and should never approach her except her season. He should observe the ordinances of the scriptures, should not be cunning and deceitful. He should be abstemious in diet, devoted to the gods, grateful, mild, destitute of cruelty, and forgiving. He should be of a tranquil heart, tractable and attentive in making offerings to the gods and the Pitris. He should always be hospitable to the Brahmanas. He should be without pride, and his charity should not be confined to any one sect. He should also be always devoted to the performance of the Vedic rites. In this connection, the illustrious and great Rishis cite a verse sung by Narayana himself, of grave import and endued with high ascetic merit. Listen to me as I repeat it.--'By truth, simplicity, worship of guests, acquisition of morality and profit, and enjoyment of one's own wedded wives, one should enjoy diverse kinds of happiness both here and hereafter.' The great Rishis have said that support of sons and wives, and study of the Vedas, form the duties of those that lead this high mode of life. That Brahmana who, always engaged in the performance of sacrifices, duly goes through this mode of life and properly discharges all its duties, obtains blessed rewards in heaven. Upon his death, the rewards desired by him became deathless. Indeed, these wait upon him for eternity like menials ever on the alert to execute the commands of their master.
