📖 Origin
Time (宙) combines roof (宀) with 由. Originally "ridgepole of a house," it expanded to mean the flow of time. If 宇 is space, 宙 is time — the entire axis from past to future.
🔍 Structure
宀(roof) + 由(from) = Flow of time
由 means "from." Time flowing under a roof — generations continuing under one roof. Grandfather, father, me, son — this is 宙 (time).
🏛 宙 in Philosophy
Zhuangzi
"Past and present, going and coming — that is 宙." Time flows unceasingly, and we stand upon its current.
Buddhism
Buddhist time: from "刹那 (ksana, instant)" to "劫 (kalpa, aeon)." Even in an instant, eternity exists.
