Reality is a concept. Everyone has their own reality (if they are lucky). Most people’s reality is an illusion, a great big illusion. You automatically have to succumb to the illusion that ‘I am this body’. I am not George. I am not really George. I am this living thing that goes on, always has been, always will be, but at this time I happen to be in ‘this’ body. The body has changed; was a baby, was a young man, will soon be an old man, and I’ll be dead. The physical body will pass but this bit in the middle, that’s the only reality.
