You said: "......there is no polarity point in this case because his Pluto is conjunct his N.Node in Leo in the 9th which means that his Soul, prior to this life, has already begun to desire and focus on a variety of philosophies, religions, and metaphysics from diverse cultures in order to understand the nature of Creation."
Does this simply mean that he is meant to continue in this area, that he has further lessons in the 9th house area of life? What about the future? Is the future determined by looking at the North Node only? Would the future be dependant on the choices he makes in this life?
You said: ".....it [the polarity point] doesn't apply to his chart as it is conj the NN."
What does it mean when the polarity point does not apply in a chart?
When most others in his generation are moving toward the Pluto Polarity Point (Aquarius + house position + NN + ruler), why does it seem like he is being left behind? His South Node happens to be Aquarius. (Sorry, I don't know how to pose this question another way.)
I suppose this makes him quite unique!
An explanation or any thoughts would be appreciated.
In any chart that you see the Pluto conjunct the N.Node symbol it means that there is no polarity point for Pluto because the intention of the Soul is to continue it's evolutionary development as symbolized by the House and Sign of the Pluto/N.Node conjunction which has already been underway prior to the current life. And in any chart that one sees this will always mean, of course, that the opposite sign of that Pluto/N.Node conjunction has already been developed to the point of limiting the Soul's evolution if it remains focused on that alone. If so, then the Soul arrives at a place of Plutonian stagnation and non-growth.
So when the EA astrologer sees Pluto conjunct the N.Node in any chart it means that the entire chart, the entire evolutionary intent, is be focused upon and through that house and sign of the Pluto / N.Node conjunction. That does not mean that the S.Node in such charts does not evolve: it does. But it evolves through the focus upon the house and sign of the Pluto/N.Node conjunction.
In your friends case that means, in his individual context, his Soul evolutionary journey, as stated before, that he collected vast amounts of information from a diversity of sources relative to his underlying desire to know the truth that is responsible for the Creation itself. This is the interaction, interplay. between that S.Node in Aquarius in his 3rd House which is ruled by his Uranus/ Mars conjunction in Gemini, this of course repeats and magnifies this theme or dynamic, in the 7th House, and his 9th House Pluto/ N.Node conjunction: the search for the whole truth, the core underlying truths of Creation itself.
What his Soul has been and is intending is to discover, FROM WITHIN HIMSELF versus other people, what those core truths and principles are: the 9th House Pluto/N.Node conjunction. This is exactly where he stands in his own evolution: the next step. And this is essential because what his Soul has been doing is collecting so many ideas and philosophies and so many different people, so many external authorities, for so many lifetimes it is as if his Soul has become almost like a library within itself because of all that collected information. This becomes ever more dramatic when the EA astrologer puts the Planetary Nodes in his Chart.
The S.Node of Neptune in conjunct his S.Node of the Moon is his 3rd House. And the N.Node of Neptune is in Leo conjunct his Pluto/ N.Node conjunction in the 9th. All of this symbols of course square his Moon in Scorpio in the 12th. That S.Node of Neptune is ruled by his natal Neptune in Libra in the 11th. This, again, is repeating the prior life dynamics, themes, of seeking out all this information from a variety of groups, some of which have been extreme and fanatical: delusional and illusionary. With the Scorpio Moon in the 12th, itself ruled by Pluto in the 9th, and it's lower octave ruler, Mars, conjunct Uranus in Gemini in the 7th, some of the leaders or authorities within these groups have been extremely charismatic: so much so that they are able to convert people through the power of their personalities. These types need 'followers'. And there have been many lives in which your friend has indeed followed these types, with these delusional ideas pretending to be 'the truth'. He had done this alone, and his has done this in conjunction with partners that he as been with: the Mars, independence, with Uranus in his 7th, partners.
This joining of groups in which had these kinds of 'leaders' , the external authorities, is also seen in his chart relative to his natal Mercury in Capricorn in his 2nd house. His S.Nodes of Mercury and Venus are also conjunct that Mercury. And these are ruled by Saturn in, yes, Gemini, in his 8th House. So, in his context, you can see yet again that relative to his desires to understand the nature of truths that explain the nature of the Creation that he has subjected himself to all kinds of external authorities over a diversity of cultures and times. He in fact made himself dependent on this orientation for most of his prior lifetimes that have lead up until the most recent prior lives in which that orientation had reached an evolutionary limit which is the reason and intention of that Pluto / N.Node conjunction.
Of course it is logical to ask the question as to why his Soul did it that way. And the answer is seen in that Scorpio Moon squaring his Nodal Axis of the Moon and Neptune. Within that his Moon also in inconjuncting his Mars/Uranus in his 7th, and Uranus is the ruler of his 4th House. What all that means is that his Soul has come through parents in which one or both , given their own evolutionary capacity, did not have the ability to understand that nature of his Soul, his unique individuality. And thus he could not be loved and given too in the ways that any child naturally needs. Quite the opposite in his case: being subjected to beliefs and values , thus judgments, that had nothing to do with him. This in turn lead to all kinds of 'displaced emotions', Uranus the ruler of his 4th house inconjuncting his Scorpio Moon, of childhood that got progressively stuffed into his sub-conscious, or individuated unconscious, as he got ever older in those lives.
These displaced emotions from childhood , essentially the emotional needs to be loved and nurtured, operated within his unconsciousness in ways that lead to the external authorities , de facto parents, relative to his core desires to know and understand the natural truths that explain the Creation. The types of parents that he would come through in those lives had very limited understandings of life, limited value systems, and limited capacity to even love. The primary message he would get in those lives from such parents would essentially be the message of 'we will love you if'. Meaning if you do what we tell you to do, be who we want you to be, believe in what we want you to believe, etc. So then as an adult he would then join these groups with those types of leaders who needed to be followed and obeyed at all costs. And when he did so he was then given love and attention.
As his Soul comes through lifetimes that reached an evolutionary limit, and, as it did so, he began to rebel against these very dynamics, and the circumstantial realities that they would create. He began to create a deep conflict between those dynamics and his evolutionary need, imperative, to discover his own emotional security from within himself: the Scorpio Moon squaring the Nodal Axis of the Moon and Neptune, the inconjuncts from it to the Uranus/Mars itself. And that very evolutionary need created at the same time for him to discover, from within himself, the truths that explain the nature of the Creation. They go together: this is his Moon squaring his N.Node and Pluto in the 9th. This is seen again via his natal Mercury, now retrograde, conjunct his S.Nodes of Venus and Mercury in his 2nd house: the evolutionary need for self-reliance by rebelling against and throwing off not only external authorities who say 'follow me', but also all the ideas, information, and philosophies that have nothing to do with the actual and natural truth that explains the nature of the Creation.
His S.Node of Mars is conjunct his Venus in Sagittarius in his 1st house, and that is ruled by his Jupiter in Leo, also retrograde in his 10th house. His N.Node of Mars is in Aries, in the 5th House. And, yes, that N.Node of Mars inconjuncts his Scorpio Moon in his 12th. Here, in these symbols, you can see once again the core intention of his Pluto in Leo conjunct his N.Node in the 9th. Look at the repeating themes in these symbols. These symbols all mean the same thing: to break from from external dependencies for all the reasons that we have discussed, and to move towards a life that is defined by self reliance, inner security, inner authority, and an entire life, the circumstances of, that reflect who he naturally is as God made him to be. To become a group of one if necessary. And it means to arrive at committing to one metaphysical system, one philosophy, one cosmology that serves as a consistent anchor of integration and understanding for life itself: Pluto conjunct the N.Node in the 9th. This is essential in order to counteract the existing 'library' of all kinds of information , ideas, philosophies, etc in his head that he has collected over many lives now. That existing library can thus create great confusion and doubt about the nature of the Creation in the first place because of all the competing points of view and the perspectives that they lead too.
Not that by arriving at the one philosophy that reflects who he truly is would then be presented to anyone else as the 'only way', but the way that works for him given where he is in evolutionary terms. The very nature of the philosophy or way of understanding the nature of the Creation for him would, of itself, equal the 'relativity' of truth in the sense that they are many paths that lead to the same goal: God.
All this right now is critically important for him as the transiting Nodal axis of the Moon is now reversed relative to his natal nodal axis. The transiting S.Node right now is conjunct his N.Node, and the N.Node transit in conjunct his S.Node. And, of course, both are square his natal Moon is Scorpio. The Pluto transit, his Soul, is coming up on his Mercury, and the S.Nodes of Venus and Mercury. In essence his past is meeting his future in these symbols. It comes to a head. And the choices he now makes can be some of the most critical choices for this life. He either, once and for all, throws off the existing duplicity of his life, trying to maintain both of these realities at the same time, or he doesn't.
