The more one knows the mystery of this phenomenon the more one learns to understand that there is a world in one's self, that in one's mind there is a source of happiness and unhappiness, the source of health and illness, the source of light and darkness, and that it can be awakened, either mechanically or at will, if only one knew how to do it. Then one does not blame his ill-fortune nor complain of his fellow-man; he becomes more tolerant, more joyful, and more loving toward his neighbor, because he knows the cause of every thought and action, and he sees it all as the effect of a certain cause.
