In plain words
We are not doing them. So in the game called life we meet defeat in every way. In this game called life we must win. That is the real game. So every human being must take life as a game and go on with his daily life.
The root cause of the shortening of man's life is evil intentions, anger, envy and Ahaṅkāra
Students! We must set about restoring the ancient traditions and culture. Our life is wearing away moment by moment. And age keeps growing. We forget our duty. What more is there for us to achieve? So it is at this sacred age that we must achieve everything. Why does man's span of life grow shorter at all? We are misusing the time appointed for this body. What is it that cuts the span of life to pieces? Though man is given a life of a hundred years, if we are firm in resolve we can live the hundred years. But what turns these hundred years into three is within us. Whether to lengthen it or cut it short is in our own hands. How! The root cause of the shortening of man's life today is evil intentions, bad thoughts, anger, envy and Ahaṅkāra. Knives like these keep cutting our life to pieces day by day. Arrogance keeps shortening man's life day by day. How? Here is a proof before your eyes. Once a man gets angry, his whole body grows hot. All the blood in the body boils. It weakens every nerve in the body.
