The angel standing in the sun is illumined intelligence at the solar center of the body, the messenger of higher mind lit from within by that inner fire. The fowls flying in the midst of heaven are the thoughts moving through the upper region of a person, the mental faculties in the head that answer when the sun-center calls. The supper of the great God is the taking in and consuming of the lower nature, the feast where the risen power devours what has been slain in the flesh.
Gathered to that meal, the mind consumes the remains of the base life and turns it into fuel for the higher state. Illumination at the solar center summons the thoughts to feed on the conquered lower self.
