recess, rest, relax, repose
憩 centers on taking a break from activity to recover ease: a recess, a rest, or a moment of relaxation and repose.
憩 combines 舌 (tongue) with 自 (self) and 心 (heart), suggesting a person calming their own heart and tongue, i.e., resting. The exact historical development is uncertain, but the component arrangement likely expresses inner quiet.
Picture your tongue (舌) and your own self (自) with your heart (心) at ease: you are taking a restful recess.
For ケイ, imagine resting under a shady tree with a cool drink, like a relaxing 'kay' (ケイ) sound of contentment.
