When Lord Caitanya finished His instructions to Śrī Sanātana Gosvāmī, Sanātana, being empowered and enlightened, was so transcendentally pleased that he at once fell at the feet of Lord Caitanya and said: "I am born of a very low family, and I have always associated with lowly people; therefore I am the lowest of sinners. Yet You are so kind that You have taught me lessons which are not even understood by Lord Brahmā, the greatest being in this universe. By Your grace I have appreciated the conclusions which You have taught me, but I am so low that I cannot even touch a drop of the ocean of Your instructions. Thus if You want me, who am nothing but a lame man, to dance, then please give me Your benediction by placing Your feet on my head."
Thus Sanātana Gosvāmī prayed for the Lord's confirmation that His teachings would actually evolve in his heart by His grace. Otherwise Sanātana knew that there was no possibility of his being able to describe the Lord's teachings. The purport of this is that the ācāryas (spiritual masters) are authorized by higher authorities. Instruction alone cannot make one an expert. Unless one is blessed by the spiritual master, or the ācārya, such teachings cannot become fully manifest. Therefore one should seek the mercy of the spiritual master so that the instructions of the spiritual master can develop within oneself. After receiving the prayers of Sanātana Gosvāmī, Lord Caitanya placed His feet on the head of Sanātana and gave him His benedictions so that all His instructions would develop fully.
Thus the Lord described the ultimate stage of love of Godhead. Lord Caitanya said that such a description cannot be given very elaborately but that He had informed him as far as possible. The conclusion is that anyone who attentively hears these discourses and instructions of Lord Caitanya to Sanātana Gosvāmī very soon attains to Kṛṣṇa consciousness and engages in devotional service to the Lord.
