The Great Yogi Paramahansa Yogananda said:
The world is a stage where we are assembled to play our parts in individual, family, national, and international life. But at the summons of karmic law, we return for a rest behind the earthly scene, awaiting assignments of our next role and of a new mortal costume in which to play it. We must not dwell sorrowfully on the time when the curtain will fall and our present role will be finished. Rather we should do our best to play our great or small part willingly and excellently, that we may deserve a welcome in the bosom of God. Otherwise, we will be forced by karma to return to this earthly stage again and again until we perfect our part.
