The word Nada comes from the Sanskrit root – Nad. “Nad” means to flow. The etymological meaning of Nada is a process or a stream of consciousness. Generally, the word Nada means sound.
The Upanishads and the Vedas describe that in the beginning was nothing. There was absolutely nothing, there was non-existence in the universe – there was only sound. The sound was unending; the sound was the only existing reality. From that sound, the universe evolved, and therefore the fundamental structure of the universe is based on Nada or sound vibrations.
Music is a result of Nada. Mantra in its purest form is a manifestation of Nada. The movement of Energy (Prana) in the body is an expression of Nada. Music can be a pleasant, interesting and inspiring spiritual practice in itself – but it can also be a part of Nada Yoga. Through music, the mind can be tuned to the finest vibrations and thereby be prepared for the transcendent Nada.
“Nada is found within.
It is a music without strings which plays in the body.
It penetrates the inner and the outer
and leads you away from illusion.”
