na druhyenmanasā cāpi goṣu tā hi sukhapradāḥ |
arcayeta sadā caiva namaskāraiśca pūjayet |
dāntaḥ prītamanā nityaṃ gavāṃ vyuṣṭiṃ tathāśnute || 33 ||

Freed from grief and wrath, they pass their time there, crowned with the fruition of every wish. Persons of righteous deeds, possessed of fame, sport there in happiness, moving from place to place, O Bharata, on delightful vehicles of great beauty. Auspicious deed, bands of Apsaras always amuse them there, with music and dance. Indeed O Yudhishthira, a person goes to such regions as the reward of his making gifts of kine. Those regions which have for their lords Pushan, and the Maruts of great puissance, are attained to by givers of kine. In affluence the royal Varuna is regarded as pre-eminent. The giver of kine attains to affluence like that of Varuna himself. One should, with the steadiness of a vow, daily recite these Mantras declared by Prajapati himself (in respect of kine). Viswarupa and viz.,--Yugandharah, Surupah, Vahurupah, and Matara. --He who serves kine with reverence and who follows them with humility, succeeds in obtaining many invaluable boons from kine who become gratified with him. One should never, in even one's heart, do an injury to kine. One should, indeed, always confer happiness on them. One should, always reverence kine and worship them, with bends of one's head. He who does this, restraining his senses the while and filled with cheerfulness, succeeds in attaining to that felicity which is enjoyed by kine (and which kine alone can confer). One should for three days drink the hot urine of the cow.
