The kanji 釈 means 'explain' or 'release', and 然 is a suffix meaning 'state' or 'condition'. Together they suggest a state of having been explained or resolved. The exact historical derivation is uncertain, but the word is used in classical and modern Japanese to describe a feeling of clarity or satisfaction.
