Wings of the Soul
From JoS Wiki
All souls have wings, even those of animals. When we freed the Demons in 2002-03, they all bolted their wings, indicating their power was restored to them. Wings indicate the soul's power and are of the shoulder chakras. The ancient symbol of the Caduceus shown above is used by the American Medical Association and also the single serpent Caduceus is used for veterinary medicine.
Learning to move these wings and control them is a part of advancing the soul. When we advance in meditation, they will appear to us, often unexpectedly. When the wings of the soul appear, this indicates spiritual power and liberation of the soul.
