I have found that the greatest degree of inner tranquility comes from the development of love and compassion. The more we care for the happiness of others, the greater is our own sense of well-being. Cultivating a close, warmhearted feeling for others automatically puts the mind at ease. It is the ultimate source of success in life.
Best not to look back. Best to believe there will be happily ever afters all the way around - and so there may be; who is to say there will not be such endings? Not all boats which sail away into darkness never find the sun again, or the hand of another child; if life teaches anything at all, it teaches that there are so many happy endings that the man who believes there is no God needs his rationality called into serious question..
