You can try one beautiful experiment: just put some sand on a plate and then when somebody is playing music, put your plate with the sand on top of it. You will be surprised to see that every sound makes a change in the pattern of the sand on the plate. It goes on changing with every sound. Classical music will put all the sand in a very silent, very harmonious state; it will create a pattern of harmony. The same sand, the same plate and any stupid kind of modern music — from jazz to the skinheads — and you will be surprised that your sand is in a chaos. It loses all harmony, it loses all peacefulness, and patterns are created which show immediately to anybody disharmony, discord. A man of silence moves with a certain field of energy around him, and if you are receptive, his vibe starts touching your heart.
