"coats of skins"
When Adam dwelled in the Garden of Eden, he was dressed in the celestial garment, which is a garment of heavenly light. But when he was expelled from the Garden and became subject to the wants of this world, what is written? “The Lord God [Elohim] made coats of skins unto Adam and to his wife and clothed them” (Genesis iii. 21); for prior to this, they had garments of light—light of that light which was used in the Garden of Eden. - The Zohar
Paul in his First Letter to the Corinthians (ch. xv) says that every seed has its appropriate body—that there are many kinds of "flesh," and also Heavenly and Earthly Bodies (σώματα ἐπουράνια, καὶ σώματα ἐπίγεια). In this context, he speaks of the bodies of the Sun, Moon, and Stars, which he calls “Glories” (δόξαι), and which we may compare to the “Fiery Vesture” mentioned by Hermes—Sidereal Bodies, to use the terminology of Paracelsus. Later he refers to the Psychic and Pneumatic—or Spiritual—Body (εἰ ἐστι σῶμα ψυχικόν, ἐστι καὶ πνευματικόν), in connection with which he states that the “first birth” is into a Living Soul (ψυχὴν ζῶσαν), whereas the “second birth” is into a Vivified Spirit (πνεῦμα ζῳοποιοῦν). The “first man” is said to be of the earth, or rather of liquid earth, and hence called choic—recalling the Gnostic fourfold division into Choïc, Hylic, Psychic, and Pneumatic bodies
“The mystery of the earthly man mirrors the mystery of the Heavenly Man. Just as we see in the heavens above a covering of all things—various signs formed of stars and planets that conceal secret things and profound mysteries, studied by those wise and adept in such signs—so are these mysteries reflected in the skin (or rather the Astral Body), which covers the body of man. This skin is like the sky which covers all things—signs, features, and forms—just as the stars and planets of the sky indicate secret things and hidden mysteries.” - The Zohar
There is also a curious Rabbinical tradition concerning these “coats of skins”, which is worth quoting in this connection. It is found in the Yashar or Sepher HaYashar, “The Book of the Just,” more commonly known as “The Book of the Generations of Adam” or “The Book of the History of Man,” which was translated into French by the Chevalier P. L. B. Drach. The legend is as follows: After the death of Adam and Eve, these coats were given to Enoch, son of Jared. Enoch, at the time of his ascension to God, gave them to his son Methuselah. After Methuselah's death, Noah took them and kept them with him in the Ark. Ham stole them and hid them so well that his brothers could not find them. Ham gave them secretly to his eldest son Cush, who kept them as a mystery from his brothers and sons. When Nimrod reached the age of twenty, Cush clothed him with these vestures, which gave him extraordinary strength. It was only when Nimrod was stripped of this garment that he could be killed. We have all heard of Joseph’s “coat of many colours” (χιτῶνα ποικίλον, as rendered in the Septuagint)—but could it be that this is a symbolic Garment of the Soul, woven of a warp and woof of Spirit?
Just as the prismatic rays originate from a physical beam of sunlight, so too do the beams from the Spiritual Sun. Such again is the Garment that all must be clothed in when the King-Initiate comes in to inspect the guests, as we are told in the Gospel according to Matthew. This “wedding garment” (ἔνδυμα γάμου) is no mortal dress, but a Garment of the Soul, a very real Vesture that we have to weave for ourselves. It must be “a coat (χιτών) … without seam, woven from the top throughout,” the same which Joseph’s brethren brought back to his Father (Âtmâ) when they had sold the Beloved Son (Manas) into the slavery of incarnation in the Egypt of the body, and for which the soldiers cast lots when the Christ is crucified. - GRS Mead
Pistis-Sophia, the three vestures of the Glorified Christos or perfected man
And the Disciples saw not Jesus because of the great Light with which he was surrounded, or which proceeded from him. For their eyes were darkened because of it. But they gazed upon the Light only, shooting forth great rays of light. Nor were the rays equal to one another, and the Light was of divers modes and various aspect, from the lower to the higher part thereof, each ray more admirable than its fellow in infinite manner, in the great radiance of the immeasurable Light. It stretched from the earth to the heaven. It was of three degrees, one surpassing the other in infinite manner. The second, which was in the midst, excelled the first which was below it, and the third, the most admirable of all, surpassed the other twain. The Initiate explains this mystery to his Disciples as follows: Rejoice, therefore, in that the time is come that I should put on my Vesture. Lo! I have put on my Vesture and all power has been given me by the First Mystery. Yet a little while and I will tell you every Mystery and every Completion; henceforth from this hour I will conceal naught from you, but in Perfection will I perfect you in all Completion, and all Perfectioning and every Mystery, which indeed are the End of all Ends, and the Completion of all Completions, and the Wisdom (Gnosis) of all Wisdoms. Hearken! I will tell you all things which have befallen me. It came to pass, when the sun had risen in the places of the East, a great Stream of Light descended, in which was my Vesture, which I placed in the Four-and-twentieth Mystery. And I found the Mystery in my Vesture written in Five Words… Words, which pertain to the Height. ZAMA ZAMA OZZA RACHAMA OZAI! And this is the interpretation thereof: The Mystery which is without in the World, because of which the Universe was made, is all Evolution and all Progress; it projected all emanations and all things therein. Because of it every Mystery exists at the Regions [Lokas] thereof. Come to us, for we are thy fellow members. We are all one with thee. We are one and the same, and thou art one and the same. It is the First Mystery, which was from the beginning in the Ineffable, before it came forth therefrom; and Its Name is all of us. Now, therefore, we all live together for thee at the last Limit; which also is the last Mystery from the Interiors. That also is a part of us. Now, therefore, we have sent thee thy Vesture, which indeed is thine from the beginning, which thou didst place in the last Limit, which also is the last Mystery from the Interiors, until its time should be fulfilled according to the command of the First Mystery. Lo! its time being now completed, I will give it thee. Come to us! For we all stand by thee to clothe thee with the First Mystery, and all its Glory by command of the same, because that the First Mystery, coming into manifestation, gave us two Vestures to clothe thee besides the one, which we have sent thee, since thou art worthy of them and art prior to us and came into being before us. For this cause therefore, the First Mystery sent for thee through us the Mystery of all its Glory, two Vestures.
