rest, take rest
憇 centers on pausing activity to recover: resting or taking a break.
憇 is a variant form of 憩, combining 甜 (sweet) and 心 (heart) to suggest a sweet, restful state of mind. The exact historical development is uncertain.
The top part 甜 suggests sweetness, and the bottom 心 is the heart. Imagine a sweet, calm heart taking a rest.
For ケイ, picture resting under a shady tree with a cool drink, like a relaxing 'kay' (ケイ) day by the lake.
