Pretty good.
The first bit carves deep into your psyche - unveiling new thoughts and emotions. Next, you understand all planes of reality -- seeing each planet, microbe, and atom. Your brain heats with the exponential growth of chemical activity. Finally, you transcend all 5 planes of reality. Your head glows at ~5,000°K. You enter the metaspace, where your head ruptures. This creates a hole in the universe, which instantly swallows itself, destroying all life. A tear falls from your eye.
