Look at the signs where the planets are placed. The sign ruler is their dispositor. It's like a command chain. You can start with any planet, you'll end up to the final dispositor if you follow the line.
Just look at the chart of Bruce Lee. He has a Saggy Sun -> Jupiter in Taurus -> Venus in Scorpio.
Any planets you look at, you'll end up in Scorpio. He has domicile Mars in Scorpio, so it's the final dispositor of his chart.
I also have Mars in Scorpio but I have Mercury in Taurus and Venus in Gemini. They are in mutual reception. That's why I'm rather soft and intellectual than a Kung Fu master like Bruce Lee
Ok so I think I’ve done it correctly. Libra has Saturn Jupiter and Pluto.
cap is in 4th ruler is Saturn which is in libra
Venus is in sag which belongs to Jupiter which is in libra
Scorpio is in 3rd which belongs to Pluto which is in libra
Moon is in Leo sun is in cap ruler Saturn is in Libra
Libra ruler is Venus
So is this right then
