Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. Thatโs all it takes. You donโt have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you. In this whole, wide world, the only thing that treats me so kindly is math.
Haruki MurakamiIn dreams you don't need to make any distinctions between things. Not at all. Boundaries don't exist. So in dreams there are hardly ever collisions. Even if there are, they don't hurt. Reality is different. Reality bites. Reality, reality.
