Aeons and calamity with 劫
劫 is a concept originating from Buddhism that represents an incredibly long, near-infinite period of time. It is a translation of the Sanskrit word kalpa, which serves as the largest unit of time in ancient Indian cosmology. In its literal Chinese character origins, 劫 can mean “to threaten”, “rob”, or “plunder”.
Etymology
This kanji is a phono-semantic compound made from 力 (force) as the semantic component and 去 (depart) as the phonetic component, giving the meaning “using physical force to stop someone who is trying to leave”.
The Buddhist meaning came separately through 劫波, a Chinese transliteration of Sanskrit kalpa. As the short form of that word, 劫 came to mean a vast cosmic aeon.
Aversion
億劫 (Troublesome)
億劫 describes a feeling of reluctance, sluggishness, or finding something too much of a hassle to do. It is used when you lack the motivation to start a task because it feels mentally or physically burdensome.
It combines 億 (immense number) with 劫 (aeon) to show something that feels endlessly burdensome.
