composure
恬 centers on a calm, untroubled state of mind: composure, serenity, and inner peace.
恬 combines 忄 (heart/mind) with 舌 (tongue), likely suggesting a quiet tongue and a calm heart. The exact historical development is uncertain.
The heart radical 忄 beside the tongue 舌 suggests a mind so calm that even the tongue is still. Picture a serene person whose heart and tongue are both at rest.
For テン, imagine a calm person sitting under a tent, completely composed: tent -> テン, and the peaceful scene matches the kanji's meaning.
