It's the opposite actually! In Placidus, my Sun is in the 6th house and my Cap Saturn is in the 3rd house but conjunct the IC. In whole signs, my Sun is in the 7th house, and Saturn is in the 4th. I usually interpret my Saturn from both the 3rd and 4th house since both descriptions ring true.
Sorry, I've been sick with a cold combined with allergies acting up for the past few days and I'm kinda fuzzy when I'm over the counter drugs. I do love cough drops from Ricola though. What I meant was, Cap Saturn in the 4th house squares Aries Sun in the 7th house. Sun must be close to DC and Saturn is close to IC.
In the interest of chart systems, I only use Whole Signs. If you want to get an accurate reading on your chart, normally I would suggest to everyone to use Whole Signs but I'm very apathetic lately and don't really care who uses what anymore...basically speaking, pick a system and stick with it and get really good at that one system.
As a general thing, if anyone wishes to enlist my "help" they're going to get the Whole Signs interpretation and if I go further, which I have the silly tendency of doing, I deal with Chaldean stuff.
What you said about Libra interacting well with Saturnine energy is quite true! Technically, Cap Saturn squares my Libra ASC, but I find that my Libra side can generally go along with Saturn's requirements even though Libra and Cap are in no way similar, LOL. I usually blame my Libra ASC on my being insecure and unhappy with the way I look, but I find that, yeah, Libra can more easily accept Saturn's decrees of, "Well, if you're unhappy with something, develop a plan to change it and follow through."
That's ok that Saturn squares your Asc. All that really means is that Saturn modifies your appearance so you are going to be on the self-conscious side (who isn't right?) and critique yourself harshly. There's beauty in that because as you've said, you're unhappy about something, change it. Do something, don't whine. The nice thing about that is, the more you do, the better you'll feel. Your problems are easy to solve when Saturn touches those planets. Everything becomes concrete and easier to pinpoint.
On the personality front, Saturn square Asc, it "edits" or "censors" whichever word you prefer, your behavior in how you wish to be perceived by others. You try to be careful in your ways of dealing with others and worried that you're not perceived to be polite, caring, courteous. You're not a typical Aries. Actually, NO Aries Sun is typical if they have Libra rising... their Sun is totally in the mercy of the Moon's house (7th house) which softens the jagged Aries ego by a few shades. What's wrong with that? Do you want to be arrogant and ridiculous with an over bloated ego that annoys everyone? Typical Aries people don't even realize they are this way until it's too late.
Cap and Aries are similar in the sense they both want CONTROL! It's cardinal and with that comes ambition. Cap is refined ambition concerned with the material plane, whereas Aries is raw energy that seeks to make a name for itself. Aries and Cap will go toe to toe against each other because they are in the running for the same thing- to be #1 on the material plane. Aside from the control thing, they express everything so differently, so yeah, your Sun and Saturn (who are natural enemies to begin with) are square and do battle. It's an odd thing... being that Sun is exalted and Saturn is domiciled. Ever looked at faces/decans and terms? That will tell you who's in charge of who...
You're right. I've also noticed that Libra and Cap work quite well together, even if they do square. But it's a softer square. Although both are cardinal, Libra wishes to control the social sphere, whereas, Cap wants to control their professional/status sphere. They move in the same line of ambition, yet separate circles so they don't really bump into each other. Cap doesn't care about social maneuvers unless it has something to do its status. Libra isn't interested in the professional sphere because it's too specific...Libra just wants to be the belle of the ball and hailed as the social leader of the pack. If anything, Cap and Libra would get together and make a good partnership.
I always find that Aries Sun, esp those with Aries rising, which means their Sun could be on the AC (good lord, help us all!), are too diva and dramatic. The only way they calm down is if they end up with an introverted rising (such as Cap or Scorpio) or a softer rising (like Cancer or Libra) and have other elements in their chart that's NOT Fire (preferably Earth to ground them). Otherwise, too much you'd get another Blue Beard like Henri Landru. Look at all that Aries and Grand Fire Trine in there! He murdered like 12 women or 15... I forget, but he was a serial killer and they never did find the bodies as he incinerated them and killed one of those women's sons. Anyway, I digress.
My Aries Sun on the other hand has a muuuuch harder time with Cap/Saturn. My Sun seems to want to identify with hardcore/strong/aggressive energies, so I have a hard time accepting discipline and restriction into how I feel about myself. In other words, I CAN work very hard and be very disciplined with certain goals but those traits don't feel natural and integrated the way that 'LET'S DO IT NOW!' Aries-style energy does. I feel like Cap/Saturn traits are just things I temporarily embody to get what I want--not characteristics that I describe me as a person.
It $ucks because I have immense respect for Saturnine people and Saturnine traits. Pretty much all of the "success" I've received in my life thus far has been due to Saturnine work. But sometimes it seems like I only recognize Saturn in others and 'borrow' his characteristics when I need them, so to speak.
I assume that you're an Aries of 89? If I'm on the money, which I usually am, you've not had your Saturn's return yet. That's when your Saturn will fully get activated and you might find better ways to connect that energy. There's no crime or shame into giving into your impatience and Ariesness. What's wrong with being high energy? It's a good way to be. Quite frankly, I'm surprised you're not an arrogant diva like all Aries before they've had Saturn's return knock the heck out of them. Majority of Aries don't learn the concept of being humble, let alone word until Saturn gets through with them and that's really a rude awakening. Saturn is really mean (not mean spirited, just mean) towards every sign and maybe he likes Air signs the most, but I think Saturn likes to be really mean towards Aries and Cancer Sun...which is probably why I notice the drastic difference in their behaviors pre and post Saturn return.
Even during my Return I felt the wind knocked out of me (literally and figuratively) or I was overly suffocated by too much wind. I wasn't spared. It was a very lonely and difficult time. My return wasn't a cakewalk.
Oy! Long story made short: how about we trade? I'll take your Sun trine Saturn and exalted Saturn on the ASC. And you can take my Sun square Saturn, Saturn square ASC/DESC, and Saturn opposite MC, LOL.
HAHAHAHAHAHA no, you don't want it! It's really heavy duty censorship and hardships. When I was a kid, I was all prim and proper...except I exploded a lot just because I really am an explosive person underneath. I tried to do the right thing all the time, but it didn't work out in favor most of the time. I couldn't stand most people because I think they're backstabbers and really too self-serving. I was also depressed and disappointed by others. I couldn't trust anyone, and I certainly didn't trust or love my parents who sent me away often. I had no security net, no sense of real belonging, and I was always on the go not necessarily because I had to be but because I never felt welcomed. I am detached from everyone and everything...except my cat, and I'm a cranky old lady trapped inside a young body who dreams of nothing but retirement that probably won't happen for another 60 years. It's very easy for me to apathetic and not give a rat's @ss and although I use to care about people and wanted to save them from making horrible mistakes, I've acquiesced that you cannot save others from themselves and no amount of love can change a rotten person to
so better let others stay where are and move on. All this may sound sharply sarcastic and funny because I like to laugh about everything, but I have a really dark sense of humor and because I'm always realistic about everything because deep down, I'm disgusted by a lot in life, but I have to soldier on like all of us,only I'm conscious of the dirty plays people make and find it wrong that life is the way it is...and yet I must accept all the sh!t I cannot change.
NOOOOOOO>>>>you definitely don't want what I've got. It can lead pretty much anyone into depression, except oddly for me, I'm not depressed... I just laugh at it all as one big joke.
