CC Madhya 24.328
kṛṣṇa sei sei tomā karābe sphuraṇa
Śrī Caitanya Mahāprabhu replied, “Whatever you want to do you will be able to do correctly by Lord Kṛṣṇa’s favor. He will manifest the real 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.
