If I do not exist, I have no perception. I am nothing. Therefore, I can not perceive. And if I can not perceive, nothing exists in my reality. Things may exist in others' realities, but I can not know of their perception if I do not exist. And if I exist, then it is my perception which creates everything. For something to exist, I have to be able to perceive it.

We are all living together, right here, right now. Humans, animals, plants, everyone and everything. We are all sharing the same reality. We are all one. And although we each have our own unique perception of that reality, it is our collective perception which creates the world. We are both seperate and together at the same time, like the cells in our bodies.
