Hi SR..

I guess perhaps this man drinks "on the rock" before taking a walk so he stumbles over the rock ;-))...just kidding..SR.

Here come ...what I've learnt from your post. Thanks SR...

The rock still be just a rock like Dhama. Nothing wrong with the rock itself only the man whose perception has changed towards his judgment over things around him.

Sorry SR I'm just practicing Buddism bit by bit :-)) correct me please  as  I need to learn more as well.
