1. Glories of the maha-mantra

    Vedic evidence is called sabda-brahma. The real essence of sabda-brahma is the chanting of the Hare Krsna mantra. By vibrating this transcendental sound, the meaning of everything, both material and spiritual, is revealed. This Hare Krsna is nondifferent from the Personality of Godhead.
