It is good to think of life in this light. The larger the number of legs the greater the bondage, the tighter the restriction. Now, suppose he marries. The attachments of the world are shortlived. So too, when one departs from this world the love one had for others and the joy, pain and happiness one had through that love, will be forgotten.
Man is everywhere plunged in worry, all the twentyfour hours.
Learn, therefore, to spread a smile on the faces of the desperate. Keep smiling yourself and make others smile. So do not worry over-much about things of the world. Worry ends in meaningless hurry and waste of time. That time is better used in meditating on God.
