gavāṃ śatasahasrebhyo dadyādekāṃ payasvinīm
putrāndārāṃstathā bhṛtyān gaurekā prati tārayet //

At the time of his re-birth, the very same cow saves him from hell. He is born in Uttara-Kuru, and enjoys a long life. One who makes a gift of only one milch cow of his many thousands, that same cow helps the donor, his son, wife and kinsmen, to cross the sea of troubles with ease.—21.
