I am a very insignificant living being, like a small red-beaked bird. Just as such a bird drinks the water of the sea to quench its thirst, so I have touched only a drop of the ocean of Śrī Caitanya Mahāprabhu’s pastimes. From this example, you may all understand how expansive are the pastimes of Śrī Caitanya Mahāprabhu.
