Omkar chanting improves the memory power. It increases the mental strengths. It arouses the Kundalini.
How to do this:
Omkar is very significant in our lives. The letters A, U and M collectively make this word. Om should be chanted for introspection, produce energy in the body and circulate the strength.
Inhale and chant A (ahhhh), then slowly closing the mouth and say U (ooooo) and then close and say M (immmm).
Stressing on the letter A, U and M cures the diseases of stomach, chest and brain respectively.
It is useful for improving the memory power.
