You may give them your love but not your thoughts,
For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of to-morrow, which you cannot visit, not even in your dreams.
You may strive to be like them, but seek not to make them like you.
For life goes not backward not tarries with yesterday.
Gibran Kahlil Gibran
Few times I have read a book of such a rare beauty. Read it aloud, and your awe will grow and grow. Absoluterly a must-read.
