Krishna is a Sanskrit name of God meaning "all attractive", and Rama is another name meaning "reservoir of pleasure". The divine energy of God is addressed as Hare. Vedic knowledge teaches that since we are all constitutionally servants of God, the chanting of His names is not an artificial imposition on the mind but is as natural as a child calling for its mother.
