On the plea of disturbance of the bodily air and metabolism, Sri Caitanya Mahaprabhu acted as if crazy. Thus in His school He began to explain the grammar of verbs through Krsna consciousness. Explaining everything in grammar in relationship to Krsna, the Lord induced His students to refrain from worldly education, for it is better to become Krsna conscious and in this way attain the highest perfectional platform of education. On these grounds, Sri Jiva Gosvami later compiled the grammar entitled Hari-namamrta-vyakarana. People in general consider such explanations crazy. Therefore the Lord's purpose in His attitude of craziness was to explain that there is nothing within our experience but Krsna consciousness, for everything may be dovetailed with Krsna consciousness. These pastimes of Lord Caitanya Mahaprabhu have been very vividly described in the Caitanya-bhagavata, Madhya-khanda, Chapter One.
