regret, repent, confess sins
懺 centers on deep remorse and the act of acknowledging wrongdoing: regretting past actions, repenting, and confessing sins.
懺 combines 忄 (heart/mind) with 韱, which likely contributes the sound and may relate to cutting or piercing, suggesting a heart pierced by remorse. The exact historical development of 韱 is uncertain.
The heart radical 忄 beside the complex 韱 suggests a heart tangled in sharp, piercing regret. Picture a heart being pricked by many small needles of guilt, leading to confession.
For ザン, imagine a person named Zan kneeling in a confessional, full of regret: Zan -> ザン, and his heart is heavy with remorse.
