The word mantra is derived from two Sanskrit words – ‘man’ meaning mind, and ‘tra’ meaning tool. Mantra meditation is used to protect practitioners from a constant onslaught of unhealthy and repetitive thoughts. A purified intellect reflecting the Atmic light confers true wisdom. When the intellect is full of God, naturally one will follow the correct path and experience Peace and Bliss. If the mind follows the senses, one is ruined. Hence, meditation is of use.
