Brâhmaṇas should be given the five gems, along with a vase of water, and a black cow, gold and different kinds of cloths. If the worshipper be not a position to give away all that, he should give a cow at all events. Close-fistedness should not be exercised in charity, for it leads to sin. One who observes the Kṛiṣṇâṣṭamî fast according to the rules laid down, enjoys happiness after being venerated by the Devas, for 307 kalpas, in the region of Śiva.—10-11.
