I have read that the transit of Pluto square Pluto tends to be one of the most trying or testing times in one's entire life. Your greatest fears, insecurities, secrets and complexes can come to the surface, forcing you to acknowledge and deal with them.
If you have already had this transit, how did you experience it? Was it a painful, traumatic time for you?
I will get it in a few years' time, and have Pluto in the 12th house natally. It will be moving through my 3rd house at the time of the transit.
What should I expect? Do you think it's anything to fear?
Well, looks like you're improving marginally. At least you mentioned the Houses. How about those little decorative thingies on the outside of the chart-wheel, you know the Signs? Don't the Signs get no love?
"Astrology by Polling" is magnificent, but it is not Astrology.
Astrology is Planet, Sign, House, Aspect, Reception. Always.
How people are affected by a particular transiting Planet in aspect with a natal Planet depends on, guess what? Planet, Sign, House, Aspect and Reception.
Reception is not an issue here, since Pluto rules nothing. And avoid the astroweb-sites, because they're all wrong.
When I had Pluto square Pluto, I left the US and went tot he UK to work. I lived in Queens Park, right on Brondesberry or Brondesberry Villas (I can't remember which) and I rode the tube to Camden Town to work for a video production company. Lot of fun. I was consulting for them since I have certain special knowledge in "things nuclear" that only a few people walking the planet know. I got to mix the sound tracks on documentaries and do the graphics. It was a lot of fun. There was an old sergeant major that hung out at one of the pubs on Kilburn High Road and he was in II Queen's Infantry at Verden. We didn't know each other, but we knew a lot of the same people there, plus a few people with the Green Jackets at Celle and both of us used to hang out at Bill Bailey's Beer Bar in Fallingbostel when we were training at Bergen-Belsen. I got to go study at the British Museum at St Pancras/King's Cross. Found Kensington has a lot of nice restaurants. Used to go there quite a bit. I accidentally tripped over Anne Boleyn's head at the Tower of London and her ghost chased me round and round for a while.
Any of that sound fearful, frightening, insecure?
Okay, so my passport expired and the idiots at US Embassy London told me I had to leave the UK, go to another US Embassy/Consulate, get a passport made there, and then come back.
No problemo. Hopped the ferry, took the train to Hamburg, got the new passport, and then of course I couldn't resist stopping in Osterholz-Sharmbeck to eat at my favorite Greek restaurant in the whole world (even better than the ones in Greece I ate at).
Anything insecure or frightening there?
Maybe I should mention transiting Pluto was in my 1st House, and another "minor detail" would be natal Pluto in the 10th House, and another "minor detail" would be natal Moon in exact opposition to natal Pluto, and I suppose I should mention that Moon rules the 9th House of long distance travel and all things foreign, and it might be helpful to mention that natal Moon conjuncts natal Jupiter and that Jupiter (not Neptune) rules Pisces and Jupiter receives Moon, and that Jupiter is the Exaltation Ruler of the 9th House of foreign travel thingies, and that Venus makes an applying trine to both Moon and Jupiter and Moon and Jupiter both receive Venus by Rulership and Exaltation and Venus receives both Moon and Jupiter by Exaltation ie Mutual Reception (and Jupiter is the natural ruler of the 9th House and a general significator of things foreign plus wealth and religion/education and such). And natal Pluto is in the Term of Venus and that helps with Venus
So transiting Pluto activated a T-Square (and of course with transiting Pluto in the 1st House you focus on the empty part of the T-Square which is the 7th House).
Yeah, I was so frightened I jumped on a bus with a bunch of Czechs and went to Praha, and then I hitchhiked to Bratislava, and took a train to Romania for the very last total Solar Eclipse of the 20th Century. And I stood right there in the exact center of the eclipse path and watched the entire eclipse move right over me.
Sorry, nothing happened (well of course nothing happened -- that's Astrology).
Then transiting Pluto squared Jupiter. Scary square? Nope. That's a mother beautiful square, because Jupiter receives Pluto in Sagittarius. That's what challenges and motivates and drives you and gives you energy. And more than that, Pluto at 10° Sagittarius is in the Term of Jupiter. That's like a double mother beautiful square. So many positive waves. Those kinds of squares are to die for.
So you can pay attention to goofball texts and websites or read the chart, look at the Signs and Houses, look for Reception, look at the Term Rulers follow the dots/connect the dots.
I understand it isn't easy. Somebody found a big rock in space, and named it Pluto, then they tried to crow-bar the Planet into fitting the "god of the underworld" description of Pluto and guess what? It doesn't work.
Some people are starting to figure out what traditional astrologers have known all along.
Astrology is an individual thing, not a group thing, so no one will have the same experiences, which is why it is all the more important to actually read the chart. Your natal chart isn't about you, it's about your world, and while this might come as a surprise to some of you, that includes other people in addition to you. So just because you see an aspect, don't make the mistake of automatically assuming it's all about you, because it isn't, it's about your world (which includes other people). Yes, it might be about you or something that happens to you, but it could be something that happens to someone else and affects you indirectly.
Maybe the 5th House is involved, but that could be your children or firstborn child and not you. Of course if you don't have children, then you can rule that out. It could be something to do with your mother (since 5th House is her 8th House). Could also be your spouse's friends. Maybe your parent's lose their home, or it is damaged or destroyed, since the 4th House is parents and the 5th House is the second House from the 4th House and so that's their assets (and in that case you'd want to pay attention to what is happening in the 7th House since that is their 4th House/Real Estate). The 1st House is your father's career or status or honor/reputation (because it's the tenth House from the 4th House).
Make sure you consider all the meanings of the Houses and derived meanings as well.
There are a lot of things going on in your chart, aside from transits that have more of an impact than transits. Those of you who think Pluto square Pluto actually did something, it probably didn't. Your progressed Ascendant in the Term of a Planet in bad condition in your natal chart can make your life miserable, and the Ascendant and other Chart Points directed to the square or opposition of other Planets can make your life miserable as well (or improve it greatly).
When transiting Planets are not making aspects, they are still doing things. They are in the Term of Planet and they are aspecting other Houses (and yes that's Houses and not Planets), so you need to pay attention to that stuff too, especially since it has a greater impact over all.
Here's the chart (Pluto made 3 squares between March 1998 and December 1999):
I'm scared for me.. I don't want to slip back into the nigredo, been there done with it! Can anyone just tell me something empowering about where I am sitting at on this rock right now? Within my own little neutron.. totally unsure if my electrons are coming or going (as above, so below). I understand and agree that Pluto is certainly turning out to be way more of a transcendental gateway to a whole new sh*t ton of heavenly bodies we have no idea where to begin nor what to think there's so many. That has got to mean something! Thousands upon thousands of years ancestors watched the stars and not long ago we were amazed to find they were even aware of the planets without a looking glass and then extremely relatively recently our whole collective consciousness completely blew up and multiplied 32,000 times!! (320,000 known bodies orbiting our Sun divided by the 10 formerly known planets counting our moon but not other planet's) I believe our thoughts affect how we feel and handle any aspects or challenges as well so I just went off on a tangent delivering myself a positive perspective of the big scary Pluto death Disney dog
