The Eighth House is traditionally "the House of Death."

It acquires its relationship with "the money of others (spouse, partner, open enemy)" because it is the Second House of the Seventh House.

As the "House of Death" it is actually death and resurrection. It is the end of this form of existence and the beginning of a new one. From this comes its association with "Transformation," and Sex. The Sperm and the Ovum die as individuals and combine to make a third and new life. Stars explode as supernovae and become two-legged apes practicing astrology. A man has the world fall down around his ears, and after some time, like Humpty-Dumpty, puts himself together again in a new form composed of what he always was: he transforms himself into a new creature.

The Eighth House also has to do with Healing, physical and psychological, including surgery and other drastic forms. It concerns all things "Occult" (i.e., "hidden from normal view") in nature. People whose Eighth House is active in the natal chart very often have a deep urge to "see beyond the veil."

The 8th and 12th Houses are the two "houses of infortune." Also included in this group is the 7th (partially - because a part of its content is "war and conflict, enemies") and the 6th (sickness, etc).
