“By sound vibration one becomes liberated.” By devotional service, by understanding well the Supreme Personality of Godhead, one can go to His abode and never come back again to this material condition. How is it possible? The answer is, simply by chanting His name constantly.
This is accepted by the exemplary disciple, Arjuna, who has perfectly learned the conclusion of spiritual science from the yogeśvara, the master of mystic knowledge, Kṛṣṇa. Recognizing Kṛṣṇa to be the Supreme Brahman, Arjuna addresses Him, sthāne hṛṣīkeśa…: “The world becomes joyful hearing Your name, and thus do all become attached to You.” (Bg. 11.36) The process of chanting is herein authorized as the direct means of contacting the Supreme Absolute Truth, the Personality of Godhead. Simply by chanting the holy name Kṛṣṇa, the soul is attracted by the Supreme Person, Kṛṣṇa, to go home, back to Godhead.
In the Nārada-pañcarātra it is stated that all the Vedic rituals, mantras, and understanding are compressed into the eight words Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare. Similarly, in the Kali-santaraṇa Upaniṣad it is stated that these sixteen words, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, are especially meant for counteracting the degrading and contaminating influence of this materialistic age of Kali.
