aeons; eons; an extremely long time
Buddhist term for an unimaginably long period of time, often used in the context of kalpas or cosmic cycles. Rare in everyday language.
It is said that the Buddha attained enlightenment after aeons.
From 曠 (vast, empty) and 劫 (kalpa, eon), a Buddhist term for an immeasurably long period. The exact historical derivation is uncertain.
