Mnemonic

If you think about being put in an old grave, being under all of that earth with no way out and eventually not being able to breathe due to running out of air... that's a terrifying thought, isn't it?

This kanji depicts this situation in a pictographic way — at the top we have the grave itself, and underneath is you, unable to breath.
