Nadas / Nada Yoga
(Sound, Vibration, Silent, Soundless)
There are various forms of sound. Sound, in fact, is merely a vibration, as is sight. We call “sound” that which can be apperceived by the human ears, or more accurately, by any ears.
Nadas is a form of sound that is heard within, without the aid of ears. It is a voice of conscience, the voice of your Overself.
