CC Antya 1.212, Translation and Purport:
"Although I am the lowest of men and have no knowledge, the Lord has mercifully bestowed upon me the inspiration to write transcendental literature about devotional service. Therefore I offer my obeisances at the lotus feet of Śrī Caitanya Mahāprabhu, the Supreme Personality of Godhead, who has given me the chance to write these books."
This verse is from the Bhakti-rasāmṛta-sindhu (1.1.2).
