Hello everyone.
I want to know what role the dispositor of a planet plays in defining the strength of a particular planet.
When do we look at dispositor to define the power of a planet?
Thank you
You should always look at a dispositor, often it'll tell you how that planet will act or what it has going for it or against it.
You used the example of Mars in Taurus in the 8th house ruled by Venus in Cancer on the MC. Alright.
It often helps to take all of the Astrological jargon out of things like this if you want to not lose your mind.
Let's say Mars is living in a country, Taurus, a wonderful vacation spot from what I hear.
Well, how does Mars like it there? You already know that Mars is in detriment AND he's peregrine. So in Taurus Mars hates it. His homeland of Scorpio has been in a bitter conflict with Taurus for generations, so the people in Taurus hate Mars and Mars hates them. What's more is that Mars doesn't even understand what the people in Taurus are saying (peregrine), he can't speak their language, he doesn't have any of their currency, and he's sort of wandering from place to place.
Well Venus is the queen of Taurus, but she's currently away in a different country (Cancer) where some of her family members rule (Triplicity), where she owns some land (Term), and she has a nice trade (Face).
Venus can see what's going on in her homeland of Taurus, because she can see Taurus from Cancer; the signs are in a whole sign sextile. She knows that Mars is running around in her country, and she's doing her best to communicate with her government on ways to keep Mars under control.
Meanwhile in Taurus, Mars is running around stabbing people and fighting, but thankfully Venus' message got through and she was able to get a few of the members of her government to calm Mars down a bit; but only a bit. Mars is less angry, but he's still very, very unhappy.
So in this context the dispositorship only stops Mars from being absolutely insane through tempering it a bit. Had Venus actually been in aspect with Mars, receiving it, it might have been a little better....well, maybe not if Venus received Mars from Cancer. Why? Cancer is Mars' sign of Fall; they enslave his people in Cancer, and Venus is in cahoots with the people who are enslaving his people...soooo Mars isn't really going to be open to help from Venus in Cancer, though Venus is still going to try to force Mars to be on his best behavior (through reception).
In this particular circumstance, Mars is going to be a problem regardless. Since you used the 8th house, I'd say that Mars will show a bunch of fighting and conflicts over dead people's money, and a rash nature that may contribute to a violent death.
But let's say that Venus was in Capricorn and in trine to Mars in Taurus. Well, Venus and Mars are friends in this circumstance; Venus is willing to shrug off the fact that Mars is murdering her people, and maybe every now and again Mars will listen to Venus and stop. Venus is still a part of the royal family of Capricorn (triplicity), but Mars is prime minister there. So here, Mars is in a positive relationship with a member of his own government, and thus calms down a bit, helping him out while he's in Taurus and Venus benefits from speaking one on one with the prime minister (though in this situation Mars can't really help her, Venus is actually helping him more).
So if Venus is in the 10th, representing perhaps a female authority figure of some sort (Venus in Capricorn in the 10th) stepping in to calm down a lot of the possible quarreling over inheritance (Mars in Taurus in the 8th), making them much milder. It also tempers a lot of the rash, accident prone nature of a debilitated Mars. Mars in Taurus debilitated could have actually showed someone dying in a dark place, maybe a cave. So our would be cave explorer (if Mars had been without help) may have slipped and fell to his death in a cave. Venus helping Mars out may make him a little more careful.
Your example is very close to what's happening in Adolf Hitler's natal chart. He has Venus in Taurus in the 8th house conjunct Mars in Taurus in the 8th. Venus is able to control what's happening in Taurus, but Mars is still angry through being peregrine and in detriment. Venus receives Mars by a conjunction; i.e. she watches him personally and forces him to be on his best behavior, which only stresses Mars out. Thus Mars is paranoid and violent, and indicates a death characterized by paranoia and violence. Venus rules Hitler's first house i.e. he allowed for his own death and made himself paranoid.
We all know how that ended
