It is reported from 'Ubayd ibn 'Umayr (radiAllahu anhu) that he said: "It used to be said when winter came: O people of the Qur`an, the night has become long so you can pray (more) and the day has become short for you to fast."
Your children are not your children. They are the sons and daughters of Life's longing for itself. They come through you but not from you, and though they are with you, yet they belong not to you. 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 tomorrow, 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, nor tarries with yesterday.
Heartache is good. Accept it joyously. Allow it, don't repress it. The natural tendency of the mind is to repress anything that is painful. By repressing it you will destroy something that is growing. The heart is meant to be broken. It's purpose is to melt into tears and evaporate. When the heart has evaporated exactly in the same place where the heart was, you come to know the deeper heart.
You are not aware of the consequences that would result (if you were granted what you desire) because what you seek might be to your detriment. (O soul) be conscious that your Master is more aware about your well-being than you are.
