The reality of the other person lies not in what he reveals to you but in what he cannot reveal to you. Therefore, if you would understand him, listen not to what he says but rather to what he does not say.
A friend is a person with whom I may be sincere. Before him I may think aloud. I am arrived at last in the presence of a man so real and equal, that I may drop even those undermost garments of dissimulation, courtesy, and second thought, which men never put off, and may deal with him with the simplicity and wholeness with which one chemical atom meets another.
Nahin pata tha ki zindagi mein
Aapsa bhi koi dost aayega....
Lekin agar Khuda ne bakshi Zindagi dobara
Toh aapki kasam vapas yeh dil aapki hi dosti ko chaahega
