The technique of the recitation then consists in following the overtones of the sound beyond the limits of the range of the ear, into the supersonic range picked up by those areas of consciousness usually referred to as the unconscious. One continues to listen, but not with the ear. Thus consciousness is induced to extend beyond its span, shifting its threshold with the unconscious. The classical techniques require one to repeat the prescribed mantram a given number of times: 21, 33, 101, 1001, etc.; but it is better to interrupt the sequence if one is not entirely satisfied with the sound produced. There is no point in repeating the same mistake or perpetuating the same imperfection over and over again. Do not content yourself with the sound produced. In fact, one is like the indian musician who, in guise of tuning his instrument, is actually tuning himself to the right pitch. An indian musician may take hours to tune his vina, but actually he is tuning the soul. You say the Bound, and 'Oh, no, that's not it', so you do it again and again and again, and you gradually get your soul into a condition which enables you to produce the desired sound. One feels things in one's self that one doesn't like in the sound that one produces: it's too personal or it's too harsh or there's too much ego in it or it's too inharmonious or there's something in it you don't like: All those things which you suffer from in your sense of beauty, which cause despair in the minds and hearts of men. After practicing the wazifas (mantras) listen to the harmonics in the atmosphere. Climb the ladder of the harmonics. Become yourself: pure vibration beyond space. You hear in each vibration the harmonics of that vibration, and the harmonics of the harmonics of that vibration. Float on the sea of vibrations. You are in absolute inner sound.
