The basic benefit of sound,
ant the reason it has healing qualities,
is because, if you´re willing to focus upon
something that is a sound,
not a conversation,
not an opinion,
not an problem,
not something that you are wanting to be otherwise,
then it has the same capability that meditation
does where you´re focused without resistance.
And any time you´re focused without resistance,
your natural vibration raises to a frequency that allows your physical body
to be more cooperative with itself.
That´s why you find healing characteristics in it.
It just distracts you.
