Once Upon a time, Time itself did not exist. Do you believe/Can you perceive that to be true? What if Time still does not exist? It does not, at least not the way most of us perceive it. Time does exist upon the physical, but does it above? Maybe, but in a different way from a different perspective. What if before and after are happening at the same time on another plane? The Past, Present, and Future all happening at once.
Meanwhile on the physical all we have is the Now, this moment which is ever changing. The only constant is change itself. The past is over, the future is yet to be. We are here now to learn from the Past while living in the Present in such a way as to make the Future that which we wish it to be.
