Be silent yourself. That will induce silence in others. Do not fall into the habit of shouting, talking long and loud. Reduce contacts to the minimum. Carry with you an atmosphere of quiet contemplation, wherever you happen to be. There are some who live in a perpetual hullabaloo, in a tornado of noise. Whether they are in an exhibition or a hotel or a temple, they tongues never stop. These will not proceed far on the road to reach God.

- Sri Sathya Sai Speaks,  Vol 5, Ch 4, Jan 30 1965. 

Only in the depth of silence, can the voice of God be heard. - Baba
