Mantra is a spiritual sound vibration that purifies the consciousness and awakens love of God. The chanting of the Hare Krishna mantra:
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare / Hare Rama, Hare Rama, Rama Rama, Hare Hare
is recommended in the Vedic literature as the easiest method for this age to attain spiritual realization. Krishna is the Sanskrit name of God meaning “all attractive”, and Rama is another name for God meaning “reservoir of all pleasure”. Hare refers to the divine energy of the Lord. So the Hare Krishna mantra means, “O all-attractive, all-pleasing Lord, O energy of the Lord, please engage me in Your service”.
There are two ways to chant this mantra: group chanting (kirtana) and individual chanting as on beads (japa). No strict rules apply for either method, and anyone can chant at any time.
