Sit in any meditative posture, i.e., Easy Pose or in a chair with a straight spine with a light neck lock (Jalandhar Bandh). Let the arms extend straight and rest over the knees. Make Buddhi Mudra with both hands (touch the fleshy pad of the thumb tip to the nail tip of the little finger). The other fingers are relaxed but straight. (The yogis associate Buddhi Mudra with the planet Mercury. It is for invoking mental and psychic powers of communication.)
Become completely still in the posture, both physically and mentally, like a calm ocean. Listen to the chant for a minute. Feel its rhythm in every cell. Then join in the mantra.
