Dispositor(religion, spiritualism, and occult)
A planet is the dispositor of other planets when they are located in the sign the first planet rules. For instance, if both Mercury and Mars are in the sign Taurus, then Venus, the ruler of Taurus, is the dispositor of Mercury and Mars. One would say that Mercury and Mars are “disposed by” or “disposed of by” Venus. A planet in its own sign, such as Venus in Taurus, is said to dispose itself (or, sometimes, to dispose of itself). In some charts, one can trace a chain of dispositors (e.g., Venus is the dispositor of Mercury and Mars, while Jupiter is the dispositor of Venus, and so on) until stopping at a single planet that is the final or ultimate dispositor of every other planet in the chart; such a planet is regarded as having an especially strong influence over the entire horoscope.
