Silence speaks a million words - if the "Silence" is from another person!
If you are the one being silent, then your "silence" would definitely speak a trillion words to you -
Flowing from the heart
Then through the brain
And sometimes overflowing through your eyes (nose too for some weirdos!)
those which your inner sense has to tell you -
What you really are and where you stand
To realize how you feel about yourself
And then depending on that
It would further say things to
Pamper you..
Console you..
Motivate you..
As and when applicable!
And then comes the true "inner peace" (as "Kungfu Panda" says it)!!
