Caitanya Mahaprabhu descended to give us the quickest way to go back to Godhead. He gave the example of a silversmith who uses a small hammer in his work. He must tap that hammer on the silver many, many times, and the work is tedious, but that is the only way to work carefully and precisely, analyzing his work after each strike. The process given by Caitanya Mahaprabhu is not like the silversmith, Srila Prabhupada said, but rather the blacksmith, who takes his hammer and in one blow quickly finishes his work. Caitanya Mahaprabhu did not wait for each living entity to gradually evolve through the performance of pious activities; he gave a quick and powerful method by which each living entity could become a self realized lover of God.
