Even though the chart is falling into place with all the planets in the 7th house, there might still be room to make minor improvements. In this case, it is to my benefit to also have Jupiter fall into the 5th house. The 5th house rules my children. Jupiter in rulership Pisces, a water sign, in the 5th house of children indicates that they have a right to swim. Not only do I belong at the pool, but they also belong in the water. Planets in rulership have rights. My children have the right to be there.
