The souls which have opened their eyes fully to the angelic plane and become interested in it have remained there; and it is the inhabitants of that plane that may be called angels. The souls which did not open their eyes fully on that plane only passed through it, and if they became interested in the jinn plane they remained there. Souls which went still further towards manifestation, and reached on the physical plane the ultimate call of their destiny, have opened their eyes there and have become human beings, which is the most wide awake state of all.
