Music without words means leaving behind the mind. And leaving behind the mind is meditation. Meditation returns you to the source. And the source of all is sound.
As long as I talked unceasingly about the Lord, The Lord stayed away, kept at a distance. But when I silenced my mouth, sat very still And fixed my mind at the doorway of the Lord, I was linked to the music of the Word, And all my talking came to an end.
Nada is found within. It is a music without strings which plays in the body. It penetrates the inner and outer and leads you away from illusion.
Within the body there is played Music unending, though without stringed instruments. That music of the Word pervades the entire creation. Who listens to it is freed from all illusion.
