Jupiter is the great benefic of the solar system — the planet of expansion, abundance, philosophy, and faith. It governs higher education, long journeys (physical and metaphysical), the search for meaning, and the generous impulses that draw us toward a larger life. Where Jupiter sits in the natal chart indicates where the universe tends to provide, where growth comes most naturally, and where the individual is called to develop wisdom.
The shadow of Jupiter is excess: the way in which too much of a good thing becomes its opposite. The house and sign of Jupiter also reveal where we may be prone to overconfidence, overextension, or the assumption that things will work out without sufficient effort. Jupiter's highest gift is not luck — it is the faith that enables the courage to pursue a vision larger than circumstances seem to support.
