Srila Prabhupada..."To write about the transcendental pastimes of the Supreme Personality of Godhead is not an ordinary endeavor. Unless one is empowered by the higher authorities, or advanced devotees, one cannot write transcendental literature, for all such literature must be above suspicion, or, in other words, it must have none of the defects of conditioned souls, namely, mistakes, illusions, cheating and imperfect sense perceptions.
The words of Kṛṣṇa and the disciplic succession that carries the orders of Kṛṣṇa are actually authoritative. To be empowered to write transcendental literature is a privilege in which a writer can take great pride. As a humble Vaiṣṇava, Kṛṣṇadāsa Kavirāja Gosvāmī, being thus empowered, felt very much ashamed that it was he who was to narrate the pastimes of Lord Caitanya Mahāprabhu."
