"Nitai would employ any means to make people repeat Hari's name. Chaitanya said: 'The name of God has very great sanctity. It may not produce an immediate result, but one day it must bear fruit. It is like a seed that has been left on the cornice of a building. After many days the house crumbles, and the seed falls on the earth, germinates, and at last bears fruit.'
