varjayeccaitramāse ca yaśca gandhānulepanam
śuktiṃ gandhabhṛtāṃ dattvā viprāya sitavāsasī
vāruṇaṃ padamāpnoti dṛḍhavratamidaṃ smṛtam //

One who does not use sandal, incense, etc., in the month of Chaitra and gives away mother-of-pearl, full of scent, along with a pair of white cloths, goes to the region of Varuṇa. This is (25) Dṛiḍha-Vrata.—44. One who gives up flowers and salt during Vaiśâkha, and gives away a cow, goes to the kingdom of Viṣṇu where he resides for a kalpa, and then is born a king. This is (26) Kânti-Vrata, the giver of lustre and fame.—45.
