A Vaisnava always follows the order of guru and Krsna. Sri Caitanya-caritamrta was written by Krsnadasa Kaviraja Gosvami by their mercy. Krsnadasa Kaviraja Gosvami considered all the devotees that have been mentioned to be his preceptor gurus, or spiritual masters, and Madana-gopala (Sri Madana-mohana vigraha) is Krsna Himself. Thus he took permission from both of them, and when he received the mercy of both guru and Krsna, he was able to write this great literature, Sri Caitanya-caritamrta. This example should be followed. Anyone who attempts to write about Krsna must first take permission from the spiritual master and Krsna. Krsna is situated in everyone's heart, and the spiritual master is His direct external representative. Thus Krsna is situated antar-bahih, within and without. One must first become a pure devotee by following the strict regulative principles and chanting sixteen rounds daily, and when one thinks that he is actually on the Vaisnava platform, he must then take permission from the spiritual master, and that permission must also be confirmed by Krsna from within his heart. Then, if one is very sincere and pure, he can write transcendental literature, either prose or poetry.
