Thanks Dave for your post on Sun in the 12th House. I must admit when I was younger I was quite upset with the things I read on the 12th House, thinking I was doomed. I'm not a nurse, but I work in mental health. With some further study, I hope to progress in this field.
My Mars is in Virgo in the 12th House.
My energy is driven (Mars) when focussed to notice the little details (Virgo) to find what is hidden. (12th house)
Although as a side note I would add that a challenge with this placement is to NOT always avoid conflict, and hurting other people's feelings when it leads you to not do and express what you really think and feel. With this placement there is not so much a danger of exploding (unless I really, really like you and trust you, ironically... lol
) but more there is a danger of imploding, through sublimination. For this reason, I've learnt to take the Tower in my own personal readings as symbolic of this, when it is in a future position.
This is what I love about astrology, self awareness... not excuses!
Thanks Starling for starting this off, I am finding it very helpful, for my own chart and am learning a lot from reading others responses too!
