there IS power in the spoken word. And I agree with Cid that what works for some doesn't necessarily work for others.

Let us not forget the ingredients for magic; Light, Sound and Motion.

Utterance of a sound whether a word or not has power. Again maybe a different sound for one than another, for the same effect.

Is it necessary to 'utter' sound? I don't think so when I hear drumbeats..the Mother's heartbeat.. For me, an extremely moving sound.
