This has been a very important step in my personal growth - to quiet the babbler...
The question would be - where does all the thoughts come from?
One will never know - until he tries to control them. Then he will find from where they come....
Then one may start to see there is more then one - flow of thoughts - source - If this then where are these thoughts comming from... and a wonderful journey opens up to oneself... As well as the realization that what we se and hear feed the babbler.
