Purport: 

Sanātana Gosvāmī was a pure devotee of Kṛṣṇa. A pure devotee has no business other than serving Kṛṣṇa; consequently Kṛṣṇa is always ready to help him. This benediction was given by Śrī Caitanya Mahāprabhu to Sanātana Gosvāmī, who was authorized to write Vaiṣṇava smṛti. Sanātana Gosvāmī was a pure devotee of the Lord, and through the blessings of Śrī Caitanya Mahāprabhu he was able to write the book perfectly.
