Death is another idea that we believe is an illusion because there is no concrete explanation. Being the way that we are, we don't admit things until we are faced with them. Unfortunately, death occurs with power and force and the only way to understand it , is to admit that it is real. People use the illusionary to escape from the real, but underneath all the imagination and make-believe there is truth and that truth is the reality. In the real world, many times what one believes is reality is an illusion to everyone else.
Examples are actors in a play or movie.
While observing them, one gets the impression that they are the part they play. But outside of acting and show business, in real life, they are like the rest of us. The whole idea of acting is an illusion. To act, is to hold the temporary rank or position. There are many different parts an actor can play.
