satisfaction
慊 centers on a feeling of deep satisfaction or contentment, as when a need or desire is fully met.
慊 combines the heart radical 忄 with 兼, which likely contributes the sound and may suggest the idea of holding together or completeness, leading to satisfaction.
The heart 忄 beside 兼 (which can suggest combining or holding together) gives the image of a heart that has everything it needs, fully satisfied.
For ケン, imagine a contented person named Ken, whose heart is full of satisfaction: Ken -> ケン.
