Oy Vey, I was hoping this thread had died not to be returned to light...
Your question is valid.
But it needs thought, polishing...
A chart might show that the person tends to lean toward things that go Boom
Or is clinging, and thus prone to collecting Barbie dolls
If the whole-tone of the chart is conservative, cautious....you are not likely to find a race car driver or antarctic explorer.
Bruce Lee's chart had Mars as final dispositor, Mars the Warrior. There's his passion....
And the horoscope does show this passion. But it won't be found in the way you were looking for it.
The "seer" must see the whole. Once you have taught yourself to do this, then you will be able to see the parts (whatever sort of detail you want) and understand them in relation to the whole.
I've been thinking about this for a bit now. I'm curious to how one may be able to find what one is passionate about, on a deep level, in the birth chart.
Since I'm relatively new to astrology, and don't study as much as I probably should (yet), I haven't read much on this topic.
However, I do know what I'm passionate about. In my chart we can look for which house has Scorpio as the house cusp. Scorpio being the deep, immersive, transformative, emotional, probing, transcending, etc. sign of the zodiac. I believe locating where this sign is in your chart may give you where your deeper or possibly deepest passions lie. Just speculating here...
Of course, the conditions of the ruler(s) Pluto and/or Mars will have a story to tell as well. It is interesting to me, in regards to the topic, that these two planets should be associated with passion. Mars gives the drive (or lack of) to push in the direction and Pluto possibly gives transformation, transcension, power, control, rebirth, etc. which could be important in achieving ones deeper desires.
Now in my chart Scorpio falls in house five. It's true that I'm passionate about fifth house issues! All of them. However, it has also occurred to me that possibly passion could merely be assigned to house five. That is regardless of what sign is there. Similarly house eight may have something to do with all of this as well..? I'm unsure...
I'm merely speculating and trying to generate some discussion on the matter.
What do you think? Care to share what you're passionate about and give examples of how it relates to your chart?
An interesting article I came across a while back. Might be of interest?: http://laraowen.com/articles/astrology/the-astrology-of-passion/
As for me, I have a number of passions (but not always the grounding to act on them! - Neptune). I'm very passionate about politics, activism and social justice (Mars conjunct Pallas in the 8th, Pluto in Libra in the 8th). I'm sure Uranus (my chart ruler) conjunct my MC plays a big part too. I think many many things can indicate passion. It depends what kind of passion we're talking about... (I think I'm also a passionate lover )
Great I'm glad it's able to be found so many ways!
