I should add ...as you may be unfamiliar with the Sabian Symbols or at least unfamiliar with Rudhyar's take on them...that Dane interpreted them as belonging to sets and sub-sets. The smallest of these sub-sets is of five a set, one of three, that repeats every fifteen degrees. The first five of any sign He labeled "Actional" [which repeats from degrees 16* to, and including 20*. The second set He labeled "Emotional/Cultural" and the third set, that which the above example, in the 11th degree of Gemini, is in, He labeled "Individual/Mental"
While traveling like Yeshu'a/Jesus did for those eighteen years surely seems to be "Action" it is the "Individual/Mental" that is emphasized here. As the great Edgar Cayce, the late 20th century clairvoyant whom in reality was channeling "Ascended Masters" of the "Great White Lodge" aka "The Great White Brotherhood" [please note that by "White" nothing racial is implied, rather it has to do with the Light, the Eternal White Light that emanates from the "Godhead"], of whom the legendary Saint Germain was identified as being one of those "Masters" that spoke through Edgar Cayce on occasion, that Yeshu'a?Jesus attended what were called "The Mystery Schools" and was taught "REAL" astrology in Persia, what I identify as Hatha yoga, in India, and also Sidha yoga [where-in the study and mastery of said form of yoga of occult powers are obtained] and went through some sort of initiation rite in the Great Pyramid in Egypt.
[Read the section of the book titled "POWERS" in "How To Know God. The Yoga Aphorisms of Pantanjali" interpreted by Isherwood and you will find a description of the meditation technique that bestows one the power to walk on water, which incidentally also bestows the accomplished yogi with the power to die and come back to life at will. Rather curious, isn't it?!!?]
The Part of Fortune derived from that same natal chart comes out to be in the 19th degree of Pisces of which the Sabian Symbol for is [ibid.] "A MASTER INSTRUCTS HIS DISCIPLE" which is an "Actional" Sabian Symbol...and it was what He literally had to do, put into action, to benefit from his Part of Fortune...which isn't about "Fortunes" of material wealth but rather slightly mis-interpreted as it is that which will provide the most fortuitous circumstances to allow you to fulfill your destiny.
Rudhyar perceived the 360 degrees of the Zodiac as being like "Four Acts" [like "acts" in a play] and every ninety degrees constituting one act apiece. Then He saw every fifteen degrees a one scene in that "Act"...thus six "Scenes" per "Act"
Gemini 11* is of "ACT ONE: DIFFERENTIATION... SCENE FIVE: DISCOVERY... LEVEL THREE: INDIVIDUAL/MENTAL... PHASE SEVENTY ONE ... As it is the 71st degree when counting from Aries 01* ...but all of that is really getting into the refined nuances of the Symbols and all one really needs to know, essentially, is that Astrological Parts are symbolically active. or relevant, and understand the difference of which of the three levels that particular Sabian Symbol in question is a "Part" of.
While it is said, and I do concur, that to have the Parrt of Fortune conjunct in the same Sign and degree as ones' M.C. I don't see that as also being true for ones' Part of Nemesis... it's a nemesis to the individual as for the reason it is going to take dedicated effort to overcome it...fulfill it. For example, my particular Lot of Nemesis/Part of Sudden Advance is in the 20th degree of Virgo [ibid.]
"VIRGO 20°: A CARAVAN OF CARS HEADED TO THE WEST COAST.
KEYNOTE: The need of cooperative effort in reaching any "New World" of experience.
It is difficult to know, from the original formulation of the clairvoyant's vision, the type of caravan of cars that was visualized; what seems to be clearly implied is a process in which a group of persons are journeying together — thus linking their consciousnesses and energies (the 'car' symbol) — in order to safely reach the goal of destiny. Here there is no longer any sense of competition, but an ordered and structured endeavor.
At this last stage of the five-fold sequence the past is entirely left behind; men cooperate in the great 'adventure in consciousness' in a TOTALIZATION OF PURPOSE AND EFFORT."
While this was meaningless to me until I produced the natal birth chart of Yeshu'a/Jesus and it was made clear to me that this, the presentation and explanation of it and how it is a template to understanding what is TRUTH in astrological practices...which prior to November, 2004, when I was 51 years old was something I never actually believed I was going to be able to do...and had only begun the effort in 2001... Once I read Trevor Ravencrots' book "The Cup of Destiny" and it was made clear to me that I am the fulfillment of what that book is about, i.e. Rudolf Steiner's prediction, prophecy, that Parsival would be reborn in time for the 21st century and would bring to the world the true understanding of Astrology [as I am the only one that has stepped forth that fulfills all the pre-requisites and did produce the Yeshu'a/Jesus natal chart about two and a half years before that book was even made known of to me] ...once I had read that book and my clairvoyant friend told me my destiny was to write a book on the subject and get it published...which I started to work on immediately following after I had finished reading Trevor's book, I have been at this endeavor as to as much total effort and purpose as I have been able to produce and sustain...but I have tired at times...taken days, weeks, off and do wonder if I haven't failed and that the Hermetic Lot of mine will be perceived to have been my "nemesis" at my lifes' end rather than that which provided 'sudden advancement"
Your M.C., being the 10th House cusp and also the "HOW" of the chart axis, symbolically, of the four points, the Asc., Desc., M.C., and I.C. aka the "WHO", "WHERE-TO", "HOW", and "WHY" of ONES' NATAL CHART [IN A SPIRITUAL INTERPRETATION...FOR A MUNDANE INTERPRETATION THE ROLES OF THE M.C. AND i.C. ARE SWITCHED WITH ONE ANOTHER] to have ones' symbolic nemesis share that axis point, the "HOW" of ones purposeful existence would be most burdensome, both in effort and to the mind... it would take a person of near superhuman mental and physical gist to manage such a placement...imho.
