Though I’m a traditional astrologer, I find the overlap interesting. In traditional astrology the 3rd house is more about daily rituals, including divination, one’s mental, psychic, emotional environment and the “fishtank” we find ourselves in, amongst other things. Whereas the 6th is associated with illness, struggle, hard work and labour, as well as service, amongst other things. I haven’t read this particular article, but I’ve gleaned lots of interesting insights from Alice’s writings.
