So this is recommended not only by Sanātana Gosvāmī... By Kṛṣṇa in the Bhagavad-gītā and Śukadeva Gosvāmī in Śrīmad-Bhāgavatam. Śudhyanti prabha viṣṇave namaḥ. He recommends that one, when one becomes a Vaiṣṇava by the supreme power of Viṣṇu, prabha viṣṇave namaḥ... He has got so much power that He can turn a low-grade man into a great Vaiṣṇava.
