A cat or a bee sees the world entirely differently because of how the structures in their eyes interpret the dancing particles and waves. Therefore, they see things we can’t. Cats can see in the dark. Bees can detect ultraviolet light. Their world is not the world that humans perceive. Their reality is different. But if they disregard the laws of physics and crash into a tree, they will suffer the consequences.
For people too, if we do not see a tree and smash right into it, we will learn that “reality” exists outside what we perceived, until we perceive the pain of our injuries.
Our perceptions are also easily tricked by optical illusions, mirages, and sleight of hand. And our senses can be impaired or nonexistent. If a blind person does not see a tree does that mean the tree is not real? They will find out if they walk into it. Yet even this solid tree, at the atomic level is an energetic pattern of particles and waves, vibrating at the intensity that produces the effect of solid matter.
Right now the earth is hurling through space at a dizzying rate, yet we perceive it to be standing still. It looks like the sun sinks in the west at the end of the day, when it is always in the same position while the earth is rotating. These are just a few examples of how our perceptions create our belief in a reality that is really not so.
