Astral Codex Ten
Ṛta is a Sanskrit word, so ancient that it brushes up against the origin of Indo-European languages. It’s related to English “rationality” and “arithmetic”, but also “art” and “harmony”. And “right”, both in the senses of “natural rights” and “the right answer”. And “order”. And “arete” and “aristos” and all those other Greek words about morality. And “artificial”, as in eg artificial intelligence. More speculatively “reign” and related words about rulership, and “rich” and related words about money.
