Yeah.
Some of the descriptions about my placements are not true and I don't know enough to say what other part of my chart offsets that.
Going through it again, there's some language I don't understand.
"Aspects from Saturn to the other planets, and the house and sign Saturn is in reveal where we will experience problems"
Aspects from Saturn to the other planets - what does that mean? When one of your planets is in a Saturnian sign?
If my Saturn is in one of the same signs as another planet what does that mean? Like if my Saturn and Mars both have Aquarius. That's not my chart, obviously, but what do I learn from something like that?
And then the transit table on a natal chart. What do all the types of transits mean? I still don't know how to make sense of it.
I also wish I understood better the fundamental role of each Planet and House in a chart. The descriptions on the site are very brief. Maybe it's an experience issue.
The descriptions are generalized, but that doesn't mean they are "not true". It is more like HPS Maxine, or other authors, are trying to describe one manifestation of that energy, out of many possibilities. A better way to understand their application to yourself would be to first understand the energetic theme of the example manifestation given, then consider its "analogue" in your own life.
However, as you describe, parts of your chart can also offset, or maybe "hide" other areas of your chart. It may be that the energies have not manifested in certain forms yet, compared to popular examples, or even that you may be unaware that it is even occurring.
"
Aspects from Saturn to the other planets - what does that mean?"
Aspects refer to the connections between planets within your chart. So if you look at the chart and see lines between planets, or you look at the table and see a symbol connecting the planets, such as a trine, opposition, sextile, etc, that is an aspect. The energies are connecting and acting in a certain manner with one another.
If there is a natal aspect of Saturn to the Sun, for example, this can cause the person to feel disciplined in their self-expressions, or feel that they can or should use their self-expressions for career purposes. They may feel a sense of value in being disciplined, and so on. A less harmonious expression can be feeling like their joy in life is restricted.
Two planets can share a sign or house, but not have any aspects. This means they are following a similar expression, but they are not actually influencing one another directly. It's like if you had two people on the same team, but they are not necessarily talking or coordinating, just to give a simple example.
The transits are the influence of the actual planets on your natal planets. Your natal planets are just names for representations of that energy in your soul; it is not like you have a chunk of the planet of Jupiter floating in you. However, the planet of Jupiter does exist in real life, and its energy has influence. It influences your soul in various ways, including in very direct ways during such transits.
If Jupiter transits your own Sun, this means its energies are impacting your soul, and more directly, the parts of you which pertain to your solar chakra, vitality, authority, etc. An example manifestation could be that it "expands" your authority, relative to the sign Jupiter is currently in. Maybe you see a new opportunity to gain power, or something.
As far as learning more, I would suggest reading online and comparing multiple sources. Look for professional astrologers who appear diligent. Some websites will have atrocious interpretations, so you have to use your intuition a bit. Be cautious of anything that appears to be marketed for instagram appeal, for example.
