Combust Venus is not secure in relating, it lacks confidence. Relating is about differences and seeing how those differences can be supportive. The combust venus person feels insecure in the face of differences so it wants the other to be the same, not different, but that defeats the entire purpose of relating, so it needs to develop the worht and confidence in its own value so that i can be comfortable when encountering different people.
I don't know if I would use that term spiritualize a planet. Planets are Grahas, they CAPTURE consciousness and define it. The moment its defined, spirituality is lost. We have to heal our planets, and then we have to become free from the grabbing effect they have on our consciousness so that it's not limited. So what you are saying I would see as the possible ways to heal the planet so that its functioning in a harmonious way within the person intead of being a source of pain and conflict.
