pacify, soothe, stabilize
敉 centers on calming unrest and bringing stability: pacifying a disturbance, soothing agitation, or stabilizing a volatile situation.
敉 combines 米 (rice) and 攵 (a hand holding a stick or whip). The exact historical development is uncertain, but it likely expresses the idea of using gentle authority to pacify or stabilize, perhaps through the distribution of rice or the calming gesture of a hand.
Picture a hand (攵) gently smoothing over scattered grains of rice (米) to settle them into a calm, even layer. That act of smoothing and settling represents pacifying and stabilizing.
For ミ, imagine a peaceful scene where you (me) soothe a crying child: me -> ミ, and your calming presence pacifies the room.
