How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving and tolerant of the weak and strong. Because someday in your life you will have been all of these.
The world is so unhappy because it is ignorant of the true self. Man's real nature is happiness. Happiness is inborn in the true self. Man's search for happiness is an unconscious search for his true self.
