Sri Caitanya Mahaprabhu admitted that He was speaking like a madman, which He should not have done for the understanding of those who are externally situated. Statements about Krsna's body, His characteristics and His flute would appear like a madman's statements to a mundane person. It was actually a fact that Krsna wanted to expose Himself to Sanatana Gosvami due to His specific mercy upon him. Somehow or other, Krsna explained Himself and His flute to Sanatana Gosvami through the mouth of Sri Caitanya Mahaprabhu, who appeared as though mad. Sri Caitanya Mahaprabhu admitted that He wanted to tell Sanatana Gosvami something else, but somehow or other, in a transcendental ecstasy, He spoke of a different subject matter.
