To derive the maximum benefit from chanting, it is helpful to understand the deep philosophical meaning behind the specific words of the Hare Krishna mahāmantra. The mantra is composed of three primary Sanskrit words: Hare, Krishna, and Rama.
Krishna means "the all-attractive Supreme Personality of Godhead." God, being the origin of all beauty, power, knowledge, and opulence, is naturally the most attractive person. Rama means "the reservoir of all transcendental pleasure." This indicates that the Lord is completely full of spiritual bliss and imparts that bliss to His devotees. The word Hare (the vocative form of Hara) refers to the supreme spiritual energy of the Lord, personified as Srimati Radharani, who represents the compassionate, devotional aspect of God.
Therefore, when we chant the mahāmantra, we are addressing the Lord and His internal energy. Srila Prabhupada beautifully translated the mood of the mantra: "O spiritual energy of the Lord, O Supreme Personality of Godhead, please engage me in Your pure devotional service." Unlike mundane prayers that ask for material boons, the mahāmantra is a pure, unalloyed cry of the soul begging to be reinstated in its eternal constitutional position as a loving servant of God.
