Swami Krishnananda on How to do meditation on Om?

Om is not a word; it is a vibration. It is a name for universal vibration. The whole cosmos is vibrating like this, and it started the vibration at the time of creation. You are trying to concentrate on that in your mind. You feel the sense of a universal vibration everywhere, like an electric energy emanating from the top of the universe till your heart. It vibrates everywhere. Feel deeply that the universe is vibrating through you.

You are not one person sitting; you are only a little drop in the ocean of universal force, and because you cannot think it properly, one creates a symbol in the mind.

Om, Om, Om. If you chant like this, you must feel a thrill in the body, a vibration inside every cell of the body. All the pranas will do like this, shaking, as if some electric shock is given, and you feel as if you are connected with the universal energy. To create that feeling, you recite Om like that. You should chant it properly, not quickly, with deep thought and feeling from the middle of the heart, directly.

You start with a deep sonorous sound, and slowly it tapers off, like a ripple in water. When you throw a stone in water, it makes circles which will become wider and wider. Like that, you start the vibration here. Then you feel as if it is expanding little by little, by circles, until it reaches the top of the universe.
