that boundless varieties of angels and spirit beings are necessary to perform those duties, and to fill and inhabit the mighty mosque of the world with their ranks.

Indeed, a species of the spirit beings and angels is present in every aspect, in every sphere, of the universe, each charged with a duty of worship. It may be said according to both the narrations of Hadiths and the wisdom in the order of the world that from lifeless planets and stars to raindrops, all are ships or vehicles for a kind of angel. The angels mount these vehicles with Divine permission and travel observing the Manifest World; they represent their praise and glorification.

It also may be said that certain sorts of living bodies act as aeroplanes for different kinds of spirits. From the birds of Paradise, called the Green Birds in a Hadith which says: “The spirits of the people of Paradise enter into Green Birds in the Intermediate Realm and travel around Paradise in them,”(3) to flies, each is a vehicle for a sort of spirit. The spirits enter into them at a Divine command, and through the faculties and senses of those living bodies like the eyes and ears, observe the miracles of creation in the corporeal world. They perform the particular glorification of each.
