When we look back, at the time of death, the experience of this life will seem like a dream. And—just as with our nighttime dreams—it will seem useless to have put so much effort into it. The fear we experience in a dream is gone when we wake up; feeling afraid was just an unnecessary exertion of effort causing us to lose sleep! When we look back on our lives at death, the amount of time we spent in hesitation, aggression, ignorance, selfishness, jealousy, hatred, self-preservation, and arrogance will seem like an equally useless exertion of energy. So be able to regard all of these illusory thoughts and concepts as dreams. Within this illusory existence, what, if anything, is the logic behind any stubbornness, distraction, hesitation, or habitual emotions of aggression, desire, selfishness, and jealousy? What is the use of holding on to these useless emotions within impermanence? Impermanence is the nature of everything.
