MERCURY IN THE FOURTH HOUSE gives instability to home conditions. It signifies the homeless wanderer who is always moving from place to place unless a good aspect to Saturn comes in to steady him down. This is, however, a good aspect for people engaged in mercurial occupations which require a stationary residence, such as librarian, or literary men engaged in newspaper work, employees in printing establishments, commission houses, agencies and kindred organizations. If Mercury is afflicted by Saturn the home conditions of the person will cause him a great deal of worry.
Max Heindel
