> "Let me see if I can describe it properly...he sees beauty in the inherent inequality of exchange, where two things may be traded for one another and the relative value of each, which determines the overall 'fairness' of the trade, varies greatly depending on the people involved and the goods involved. He believes that the paradox of the inherent inequality of exchange generates what he called 'sparks', sparks that he can somehow harvest because he knows of them and sees the true beauty of the exchange. He is so devoted to this belief that it has actually started to warp reality to match what he thinks. Apparently gathering enough of these sparks gives him power, enough power that he was able to switch all the currency in Gensokyo with jewels thanks to how his beliefs are warping reality, and he's going to keep harvesting sparks and exchange Gensokyo's currency-based economy for a new type of economy, one with no currency at all, where someone can trade literally anything for literally anything else."
