I'm afraid this is one of very very few terms I solved outside the PT. I didn't keep notes or bookmark these because I already have thousands of notes and bookmarks to trace where I've been and keeping these would more than double the number for only a few more words.
The word "djed" is barely used in the PT because these are the "Rituals of Ascension" and they were geared more to what people could actually see and experience while the djeds were in the hidden place operated by the blessed "dead" to protect the crowds from "serpents". Out of sight, out of mind. The same applies to the upper eye of horus in the mehet weret. While this latter gets a little more mention it is directly the cause of water flow and everyone could see the water moving in the winding watercourse.
The best mention of the djed in the PT is here;
1218b. N. drinks of that which thou drinkest.
1218c. Put thou the back of N.
1218d. against the post, against it who is before its sisters.
The dead king drinks of the waters of the abyss whose back is against the "post" and its sisters; the djeds. The beauty of these lines is that they also show important grammatical rules. Everything was both masculine and feminine dependent on perspective. The "djed" because of it shape and function (a post aiming a stream of water or atum's ejaculate) was obviously highly masculine but at the same time the interior of the post was feminine. This is exactly the same thing as atum creating the world through masturbation where his upward moving ejaculate was "shu" and was "tefnut" as it fell back down. Atum was the FIRST GOD but he still had a "consort" to create reality which was "iusaas" which was the opening through the phallic ben ben to the waters of the abyss named "nun". Despite this they also said that nun pre-existed atum!!! This doesn't show confusion or multiple origins as Egyptology believes; it shows that meaning was always dependent on perspective and from the perspective of the "back" of the standing water the djed was feminine.
The water couldn't stand properly without the djed to aim it and control it at the upper eye. Just as we need a back to stand so too did the dead king after he was transmogrified.
Anyone can understand those above two paragraphs with effort.
I could never have solved the word "post" above without first understanding the nature of the djed. These lines were critical to understanding the nature of Ancient Language and how its meaning lies in context from a stated perspective. I do remember that a lot of the meaning opened up after solving them.
Ancient people didn't talk or think like us. They used a language which was metaphysical and required understanding to speak at all.
Let me think about this a bit and I'll see if I can't recall some of the resources used for solving the "djed".
