Welcome to the EA MB.
I know when I first started posting on this board I was so excited to find out more about my chart and the aspects (and I certainly still am!), because I knew in my gut how truly profound the gift of reading your chart through EA is. The months of reading this board, prior to me actually joining this board to post, I was just astounded at the gift of this astrological paradigm. Finally, I joined in, in such anticipation. I am actually finding that EA is actually life altering when it is let in deeply.
Also, I found initially, that in trying to piece meal isolated aspects, without understanding or grokking the fundamental evolutionary signature
of my chart first, was not as useful. I don't guess or assume that this is what your doing bc I see you are starting your query with PLUTO. ---However, I just thought I would say that anyhow, for clarification purposes.
In EA interpretation, the first thing to really delve into is understanding your souls intention for this life, as you may already know by even being on this board in the first place, correct?And of course this STARTS WITH PLUTO (Your SOUL Signature)!
The very first step I took in this was to get REALLY AQUAINTED with my natal PLUTO(soul)-- by house and sign.
-- And what I mean by this is... To really grok what it meant for me, in my case, to be a Pluto in the 7th House/Virgo Soul! -- And what does this Archetype feel like? --how does this play out in this life, here? --what are it's fundamental characteristics, and where might I go unconscious? -- what are this archetypes highest and lowest vibrations, etc. etc.? You know, just getting really acquainted with the tendencies and characteristics of the Virgo/Libra Soul Archetypes here, in me (really getting into the ARCHETYPE of both Virgo, AND LIBRA, because my Pluto is in House 7 THE LIBRIAN HOUSE, hence, I also had to get familiar with the archetype of a LIBRA soul ).
For you, if this is your chart we are talking about, I would suggest, if you have not already done so, getting REAL AQUAINTED with the Archetypes of Libra and Aquarius (H11)(your SOUL ARCHETYPE(S) ) and how, as a soul signature, they play out in this life, for good or ill, and all in between, especially through the EA paradigm. (You might do a MB search here, or refer to the articles on this site, or Deva's site http://devagreen.com/deva.htm
, or the Pluto Books by Green. And, incidentally, I believe you can read some chapters right on google books through the limited preview option, if you dont have the books in your possession.)
And notice how the tendencies and desires to separate and/or merge with the Source for these/this soul archetype(s) LIBRA/AQUARIUS (or 11th house), play out, as well.
I know for me, so many deep insights and liberating experiences, came just from this alone!
It was only after I did that could I then proceed into it's polarity point and the aspects it was making, and then onto my South and North Node placements and all the other planets placements, and the aspects they were making --(opposing other planets also), etc.
As far as the specifics of your question about how a Mars in the 5th in Aries, and a Pluto in the 11th in Libra in opposition play out -- Well, this ACTUALLY IS THE VERY BASIS of your SOUL in this lifetime! That being a PLUTO IN H11 LIBRA, AND IT'S POLARITY POINT( PPP) IN ARIES H5 RULER MARS. So, How has your life been so far? This is how it has been playing out, no? My point in saying that is to express what a huge and very intimate question this is for you! It is the essence of your lifetime!
For starters with your question though, any Libra Soul will have codependency issues/karma in relating to others, both socially and one to one that have to be worked out or played out, that often are not going to be comfortable --"problems in social relations" as you put it. It's simply the grist for your soul's mill, so to speak. They are meant to direct you into the polarity point of Libra, which is obviously Aries = SELF DEPENDENT, self initiating, self actualizing, pioneering, assertive, original and innovative, true courage, etc etc. And you do have the support of Aries ruling planet MArs, right there in the 5th house (another fire sign =5th house ..being that LEO is the natural ruler of H5).
And the SOUL SIGNATURE PPP by house , would be pointing from the 11th house to the 5th house. So to know the HOUSE Archetypes of the 11th and the 5th, are key also. With your house PPP, pointing to you to embracing the qualities of H5 & I would add Self-Love to the the many characteristic,qualities and descriptions of H5, especially in your case with Aries (self)Rulership.
I did want you to keep in mind, however, that I am a bit new to EA myself, so I cannot really comment much further than this, with as much confidence --and I wish I could -- but this much that I share I feel confident in sharing with you. And I am sure the fine teachers of EA on this site will come along soon and perhaps clarify, correct or expound on anything I have shared, to better support your question.
I have no idea what your experience thus far is with EA, and perhaps you too have already worked with the basic EA premise already that I just presented, but I just thought I would mention it to you, just in case.
In Love and Grace.
PS. HOPE THIS WAS OF SOME USE TO YOU<3
