The weak can never forgive. Forgiveness is the attribute of the strong.
There is nothing that wastes the body like worry, and one who has any faith in God should be ashamed to worry about anything whatsoever.
Each one has to find his peace from within. And peace to be real must be unaffected by outside circumstances.
Always aim at complete harmony of thought and word and deed. Always aim at purifying your thoughts and everything will be well.
