But we both obey, And here give up ourselves in the full bent To lay our service freely at your feet, To be commanded.

Is giving up ourselves in the full bent a major full-on bow?
Is the full bent head to knees?
Or forehead to the floor?
Feels to me like the full bent might look a little like Child’s Pose, close to the floor, close to the self, at the feet of the sovereigns, almost kissing their toes.
