O Viṣṇu, thanks to your good qualities, you deserve worship of the gods. You are always praiseworthy. I shall explain a mantra if you have faith enough.
O Kṛṣṇa, perform the Japa of this most efficacious mantra viz. “Om Namaḥ Śivāya.” It yields all desires. It is divine. It bestows worldly pleasures and salvation.”
