Sound is shakti and dissolves in consciousness
Yatkinchin nadarupena sruyate saktireva sa /
Yas tattvanto nirakarah sa eva paramesvarah//
Whatever is heard of the nature of the mystical nada or sound is verily Shakti. That in which all the panchatattwa elements find dissolution, that is the formless being, the supreme God. (Chapter -4, Verse 102).
