Mackenzie Phillips’ surprise the media when she admits that she had what amounts to an affair with her father for ten years. There has been much debate in the news media about whether the affair was rape or not, since Mackenzie reportedly was 19 years old when the initial incident occurred. Mackenzie is the daughter of John Phillips and his first wife, Susan Adams, but John left the family when he married his second wife, Michelle Phillips, in 1962. So John was the distant father to Mackenzie, most likely idealized by her and never available.
Her astrological chart shows that she has a Scorpio Sun in tight conjunction to Mars (sexuality and aggression), both of which are squared by Uranus (shock and sudden change). That Sun/Mars conjunction has a strong sexual component, and the square to Uranus can signify a shocking early trauma, or simply a rebellious nature that relishes the shock value of radical behaviour. In any case, Uranus square the Sun often shows the sudden departure (Uranus) of the father (Sun) that leaves a gaping hole in the life of the individual.
Mackenzie’s chart is made more difficult by a square from Saturn to both the Moon and Venus. Venus in the birth chart shows where we feel attractive and deserving of love, and that square from Saturn indicates a deep insecurity and sense of rejection. The square from Saturn to the Moon, which represents emotional security and safety, exacerbates that insecurity and adds a note of isolation and loneliness.
She also has Chiron (wounding and healing) square to the Sun and directly opposite Uranus. The square of Chiron to the Sun reveals the difficulty she has had in developing a sense of Self and a healthy ego (the Sun), and the Chiron/Uranus opposition is often associated with anxiety and because it requires a transmutation of energy it can be extremely intense. It is prevalent in the charts of people who do healing work but it is also commonly found in people who have drug addictions as they seek to medicate the intensity of their experiences.
