Nothing truly exists because what is true is that which cannot be perceived and is beyond existence. Truth does not exist because existence is irrelevant to it.

Non-existence created an illusion so that it could relate to itself. From that came the illusion of existence and consciousness. From that relationship came a third, fourth, and so on.

Each illusion fluctuates in order to maintain balance. The balance is whatever expends the least amount of energy. It constantly gravitates to that point, if you will. This enables the illusion of movement, progress, whatever.

So then we have what seems to be a never-ending universe of things, ideas, etc., from these constantly-changing relationships.
