Turning your senses inwards connects you with your infinite nature. Infinite division leads towards singularity. If the Universe is expanding it must also be contracting in order to remain in equilibrium. The external part of our existence is the expansive part. Everything we see as reality is illusionary and appears convex due to the radiating electromagnetic emmisions of energy into the vacuum. The vacuum is the contractive side of the structure of reality. This concave part we don’t see because it is contracting towards infinity and moving away from us. This is why it appears as the vacuum. We live inside a black hole. It is the internal part of our existence heading towards singularity and it generates the gravitational field.
