When we sleep, how do we wake up? You just naturally emerge from consciousness to unconsciousness to consciousness naturally. Sometimes the transitions are abrupt, but sooner or later, you go through the sleep cycle, only to emerge from unconsciousness seemingly involuntarily. Death is a lot of the times, involuntary transition to unconsciousness for the rest of your life. So what's the difference between sleep and death? It's the emergence of consciousness after the period of unconsciousness that makes it a sleep. We are simulating death every time we go to sleep. Most of the times, we are acquainting ourselves with death on a daily basis. The world can end in the next 15 minutes, 5 hours, 2 weeks, 6 years, or 3 decades. The mother nature will be fine regardless of whatever we do to her. From the earth everything emerged, and to the earth everything shall return. Live the day like a gift and plant the trees for tomorrow. Death comes to us all eventually one way or another. It doesn't matter if it's the planetary apocalypse or just an accidental fall. We should do our best to lift each other up the best way possible in the meanwhile, and accept death should it happen.
