Upon making this decision, the two brothers at once took steps to leave their material engagements, and they appointed two learned brāhmaṇas to perform certain Vedic religious rituals that would enable them to achieve complete freedom for the devotional service of Kṛṣṇa. These preliminary ritualistic functions are known as puraścaryā. They require that three times a day one worship and offer respects to one's forefathers, offer oblations to a fire, and respectfully offer food to a learned brāhmaṇa. Five items—the time, the worship, the offering of respect, the offering of oblations into the fire, and the offering of food to a brāhmaṇa—constitute puraścaryā. These and other rituals are mentioned in the Hari-bhakti-vilāsa, an authoritative book of directions for Vaiṣṇavas.
