We either think of the past or the future and ruin the present. Past is past, forget it. The past which is dead and gone, is useless. Work for your progress by living in the present, and in the moment. Future does not always bring happiness. And so far as the past is concerned, how much happiness have you experienced in it? Therefore, live happily in the present. What should we do in the present? Follow this maxim: Less luggage more comfort makes travel a pleasure. We should not worry about the past at all. Thinking about the past will not do any good to us. Therefore we should lead our life in the present and achieve all-round progress. (Divine Discourse, “My Dear Students”, Vol 2, Ch 14, Aug 22, 2007)
