” Anyone, anywhere, can easily take to this Hare Kṛṣṇa movement; one need only chant the Hare Kṛṣṇa mahā-mantra, observe the rules and regulations, and stay free from the contamination of sinful life. Even if one is sinful and cannot give up sinful life immediately, if he chants the Hare Kṛṣṇa mahā-mantra with devotion and faith he will certainly be freed from all sinful activities, and his life will be successful. Paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam. This is the blessing of Lord Rāmacandra, who has appeared in this age of Kali as Lord Gaurasundara. “
