If you fall asleep and dream, you can dream that you are in another place. In the dream, the world seems vast, even infinite.

But in reality you are only ever in one place, in your bed sleeping. It is the same with our consciousness, it is a single "no-thing", from which all space and all time unfolds (though it is not space and time, but instead spacetime, which is a single thing) . All this vast reality is like a dream born from a single source.

That is what we are. That undefinable unspeakable "no-thing" from which all things are born.

If you notice, who is it that feels, thinks, dreams, loves and all the rest of it?

The answer is always "I". No matter who you ask, from the tiniest bug to the mightiest Gods, the answer is always "I". "I" therefore is all that exists, and it is the same "I" everywhere and in everyone.
