Good posture allows gravity to wear more evenly. Bones and Integrity allow Him to support our frame and our frame of mind. If we give in to the tugs of the world, time plus gravity will leave us stooped.
Pray to stand tall and honor Him.
Read scripture. Let it soak into your bones.
Meditate. Close your eyes and breathe in the opportunity of Trust.
Warriors of Light know that Integrity is what Humility becomes over time. Just as the most common sum of any roll of two dice is seven, peace of mind is the oft result of humbly maintaining the Best posture.
