Cheer Up! Stay Positive!
To err is human, To forgive divine. No one is perfect. Everybody makes mistakes. Anger will cause pain. Forgiveness will give peace.
Life, Love, Happiness, Peacefulness... these are pre-existent within. Mind rises over them, covers them, then foolishly seeks them outside and gets disappointed. By meditation and self-enquiry, disturbing thoughts are expelled, mind becomes clear, and Happiness is rediscovered.
