Hare kṛṣṇa hare kṛṣṇa kṛṣṇa kṛṣṇa hare hare, hare rāma hare rāma rāma rāma hare hare: This sixteen-name, thirty-two syllable mantra is the mahā-mantra in the age of Kali by which all living beings can be delivered. One should never abandon chanting this mahā-mantra and take to other so-called purificatory processes which are practiced by rascals, or engage in chanting other metrical compositions of the name of Kṛṣṇa that are against the pure conclusions of the scriptures, or are filled with rasṁbhāsa. About this divinely spiritual mahā-mantra, which delivers one from material existence, the original guru, Lord Brahmā, has said, kali-santaraṛādi śrutite, “The śrutis have declared this mantra to be the best means of deliverance in the age of Kali”. Having all heard this from Brahmā, the sons and disciples of Brahmā, beginning with Nārada, all accepted the Hare Kṛṣṇa mahā-mantra and, having meditated on it, attained perfection. – Ananta-Saṁhitā
