"A person who is constantly engaged in devotional service to Kṛṣṇa and who chants His holy name becomes so transcendentally attached to the chanting that his heart becomes softened without extraneous endeavor. When this happens, he exhibits transcendental ecstasies and sometimes laughs, sometimes cries, sings and dances—not exactly in an artistic way, but just like a madman."
Lord Caitanya further informed Prakāśānanda Sarasvatī: "Because I have full faith in My spiritual master's words, I am always engaged in chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. I do not exactly know how I have become just like a madman, but I believe the name of Kṛṣṇa has induced Me. I realize that the transcendental pleasure derived from chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare is just like an ocean. In comparison, all other pleasures, including the pleasure of impersonal realization, are like shallow water in channels."
