Beautiful soul, close your eyes for a moment and listen. Not to anything specific. Just listen.
Listen to whatever is present - the hum of the refrigerator, the distant traffic, the ringing in your ears, the pulse of your own blood. Listen as deeply as you can. Now listen deeper.
Past the external sounds. Past the body sounds. Into the silence beneath the sounds.
Is it actually silent? If you listen carefully enough - with the kind of attention that Nada Yoga cultivates over years of practice - you'll discover something impressive: the silence isn't silent.
