When it comes to having a planet at the very end or beginning of the cusp of a house, it can be troubling. The question raised would be, “Well, which house is this planet in?”
And I think the answer to that question doesn’t really matter, unless you want to be objective about it. By finding the answer to that question, you would probably then read descriptions about the house placement you’ve just read, and then accept that your planet in question is in one designated house and that’s it.
But I don’t think planets quite work that way… Or at least it doesn’t tell the full story. I truly believe house cusps are not meant to be strict at all. Take away the house cusps and what you see in the natal chart is a gradient of energies, the gradient of the signs working together. The house cusps are not strict walls that cage certain energies from entering another. The houses, like the signs, blend and mesh together so hence, whether a planet is in a certain house or not shouldn’t be a huge concern.
There are different house systems that will tell you different things and designate certain planets in different houses, and you have to realize the implications of those different house systems… Why are these house systems different besides the fact that the calculations are different? Why is it that in Placidus, your Sun is in the 7th, but in Whole Signs, it’s in the 6th? Would house position even matter at that point?
I think the personal reality of it is that the world does not work so… cleanly. When you see someone, you don’t JUST see their Sun in the 11th, you see their Sun in Aquarius, their Sun-Uranus aspects, their Leo ruling the 6th… it’s all just a mixture. Everything is a mixture.
The natal chart to me is like a recipe for a smoothie (lmao what a shitty analogy). But seriously, in the natal chart, you are aware of the ingredients used to make you, but in reality, you’ll only see a blend. When you drink a smoothie, you drink not just the strawberries, but the milk, ice, etc.
With that being said, I think we should be aware of the mixed energies of the chart, but we can’t also forget the separate ingredients used to make that mix. We should be tolerate of the unpredictable chaos of human self-expression yet also be tolerable of the possible components of where human self-expression comes from.
