8th versus 12th house
Rain, here are some additional thoughts about the 8th and 12th houses for you to ponder.
Along with death, rebirth and transformation, the 8th house is about secrets. These are conscious secrets, the sort we don't want our neighbors or boss to know. Or the sort of things better kept private, hence the 8th is about sex. If you think about what most folks want to keep secret, you can readily understand that the kinky bits of ourselves, what we may need to transform, are lodged in this house.
The 12th house, is that which is hidden, not what is secret. The difference is that the area of the 12th, faith, mass emotions, etc. encompasses matters which are so profound that they are difficult to express rationally, much less verbally. So these "secrets" are not the conscious secrets of the 8th, but the sort of "soul" stuff that we can only partially grapple with on a conscious level. The old texts used to call the 12th the house of hidden enemies or self undoing. It was also associated with prisons, hospitals and sanctuaries.
Both the 8th and 12th houses deal with the occult. The 8th is more about rites and practices. The 12th more about direct psychic experiences.
