This is an interesting placement. The person with Leo in 12th is a bit strange, sensitive and inscrutable. They hide in plain sight, which is to say….they are seen but not revealing anything.
Which is funny in a sense because everyone notices them, yet nobody really knows them once they think about it.
This is because this native is genius at being really talkative and friendly but, not really about topics that reveal anything personal to them. They will talk for hours about their favorite movie but, never actually reveal why it is their favorite on a personal level.
Many old school views on this placement state that this points to a previous life of success and an image they kept vigorously intact through to even death. Their image was soo important to them to the point of carrying it through into the next life. This can be wonderful or horrid depending on the type of life they lived in that previous life. A good one or a selfish one.
(Personally, given that TMW5T is born Sept 2 which is proof of a Twin Flame connection and the rules of ascension, I think this confirms a virtuous past life. I wonder who he was. Hmmmmm..)
Those with this placement are often deeply concerned with the overall good of mankind. Not a bad house to fall into really.
