Is chanting OM a part of certain religion? Does chanting have any scientific impact on the body and mind?
OM is considered the most primordial sound. It is also called the Anahata sound or the sound created by the movement of celestial bodies in the universe. It is the universal pulse of existence. One may chant OM in more than 1000 ways. Depending upon the letter you emphasize while chanting it affects various systems of the body. Chanting OM not only attunes the mind with the body and body with the breath but also leads to spiritual enlightenment. On the physical level it boosts the blood circulation, calms down the heart beat, activates and soothes the nervous system while on mental level it calms the cranial nerves, relaxes the brain, sharpens the focusing ability, gives clarity to the mind and on the spiritual front it makes the Kundalini rise in the sushmana after clearing the astral tubes.
