The ancient Egyptian Eye of Horus or wedjat ('Whole One') is a powerful symbol of protection, and is also considered to confer wisdom, health and prosperity. Horus was one of the most important Egyptian Neters, a sun-neter represented as a falcon or with the head of a hawk, whose right eye was the sun and whose left eye was the moon. He was the son of Osiris (Neter of Divine Truth and Good) and Isis (Netert of Divine Love and Creation). Osiris was slain by his own brother, the evil Set (Neter of Opposition, Darkness/Chaos), and Horus (Neter of Return/Self Actualisation) fought Set to avenge his father's death, winning the battle but losing an eye in the process. The eye was restored by the magic of the Neter of Wisdom and the moon, Thoth, and this allowed Horus to grant Osiris rebirth in the underworld. The Eye of Horus symbol was used in funerary rites and decoration, as instructed in the Egyptian Book of the Dead.

This old Egyptian symbol actually appears on the Great Seal of the United States, and on every United States dollar bill. The reason is because the original designers of the Great Seal were influenced by Freemasonry, which has roots in Ancient Egyptian Mystery School teachings. The eye within a pyramid originally represented the god enclosed, during his "dead" period, awaiting rebirth. He was entombed in the underworld. Nevertheless, his soul remained alive and watchful, as indicated by the open eye. The physical eye is to humanity what the sun is to Ra. The eye is the part of the body able to perceive light and is therefore a symbol for the spiritual ability. This is equated to the Gospels "those with eyes to see".
