Nanda Mahārāja, for the sake of the affluence of his own son Kṛṣṇa, gave the brāhmaṇas cows fully decorated with garments, flower garlands and gold necklaces. These cows, fully qualified to give ample milk, were given to the brāhmaṇas in charity, and the brāhmaṇas accepted them and bestowed blessings upon the whole family, and especially upon Kṛṣṇa.
