Ed,
You said,
"I started this thread to discuss Laurency's ideas not teach people about them, and I am certainly not trying to "convert" anyone to Laurency."--> In the end, it is about the ideas, not the person who said the ideas. You wish to discuss the ideas, and that is good.
In the other thread you said,
"One thing that really springs to mind is the confusion in Theosophy about the monad. The prefix "mon" implies that it is a single unit whereas theosophy states that it is three units (the 3 permanent atoms that make up the "higher self")."--> I would not say three, I would say two. Geoffrey Barborka, in his book
The Divine Plan, shows how the Monad is a duality, a combination of the Atma and Buddhi. Here is a graphic I put together. (DP refers to
The Divine Plan, SD refers to
The Secret Doctrine, and the i-1-1 numbers refer to specific Stanzas of Dzyan

Many people think the Monad includes a third principle, Manas, but it cannot. If you read the Theosophical history of the beginning of the human race, a big part of the story is the repeated failures of creating human Manas. While all of this failing was going on, each of our Monads was still there, waiting for our Manas to be created.
"Laurency identifies the monad as the "self" (the source of our individual consciousness and identity) not the "higher self"."--> I would agree with that. The Atma is the Higher self, so if we wish to give the Monad a title, Self (not Higher Self) would work.
"Laurency states that the purpose of life is the evolution of consciousness and as the monad/self evolves it rises up through the chain of permanent atoms (over the course of thousands of incarnations)."--> This statement agrees and disagrees with Theosophy.
"In regular human beings the monad/self is centred in one of the three permanent of the lower self (physical, astral or mental)."--> I would disagree with this statement. The Monad has its own "center", which is co-located with the astral body center, etc. The Monad cannot exist on the astral plane, physical plane. etc.
"The monads of the spiritual masters that the early theosophists learnt from (DK, KH, etc) were centred in the higher self, which is where the confusion about the monad arose."--> I feel your statement does not make sense. A Monad cannot be centered in a Higher Self. (I am assuming by Higher Self you mean Atma.)
"Incidentally some of Laurency's information came from an earlier version of Theosophy called Hylozoics which was devised by Pythagoras (an incarnation of KH)."--> Even Hylozoics is merely a re-issue of an earlier version of the Ancient Wisdom.
"It is not possible to answer your question any better than that because as I said earlier, Theosophy is like high school and laurency is like college."--> Oh, you would be surprised. We mere high schools students may be capable of more than you give us credit for. You sound like you are withholding a more detailed answer. Please feel free to share this higher information.
"When you were at high school you thought you had a pretty good grasp of the subject matter, but when you got to college you realised there was a whole new level to learn about. But no one can tell you about it - you need to go to college and discover it for yourself."--> You have repeatedly said your philosophy is superior to mine. Show me.
