Daily Dharma

Chanting meditation means keeping a not-moving mind and perceiving the sound of your own voice. Perceiving your voice means perceiving your true self or true nature. Then you and the sound are never separate, which means that you and the whole universe are never separate. Thus, to perceive our true nature is to perceive universal substance. With regular chanting, our sense of being centered gets stronger and stronger. When we are strongly centered, we can control our feelings, and thus our condition and situation.
