one can use to determine the rulership of a house: If the first house cusp is, say, 0 degrees Aries and the second house cusp is 0 degrees Taurus, the house will be ruled solely by Aries. If, for example, the second house cusp is 25 degrees Taurus and the third house cusp is 22 degrees Gemini then the 2nd house will have Venus as its primary ruler and Mercury as its secondary ruler since the majority of the house falls in Gemini. The closer the beginning of a sign is to a house cusp, the more power its planetary ruler has in that house. Some astrologers do not consider secondary rulers of houses in this type of scenario but only rulers of house cusps which are primary. If, as an example, the fourth house cusp is 25 degrees Capricorn and the fifth house cusp is 8 degrees Pisces then the house will have Aquarius intercepted. It will have Saturn as its primary ruler, but in addition to Saturn, Uranus, will play a role in the matters of the house though in a more hidden and less obvious way. Neptune will also play a role if any planets are in Pisces between 0-7 degrees. If a house cusp or angle is at 29 degrees of any sign, the following sign's ruler will be the house's co-ruler. Some apply this rule of shared rulership for angles that are 25-29 degrees of a mutable sign, within 5 degrees of a cardinal solstice or equinox point. When a person attempts to determine the rulership of a house, the more planets or bodies that rule the house, the more complex the matters of that house will be. Especially when aspects to the rulers are considered. Generally, the sign on the cusp will be the outward representation of the rulership. The ruler of the sign inside the house will not be readily apparent but will manifest itself at critical points in a person's life and in deciding life directions. Meaning, the ruler of the sign inside the house imparts its values and shares 'executive decision' making but is not involved in the actions taken or the outward expression of matters of that house. As in the case of intercepted houses, the sign that is in the middle of the house is the sign that the native must transcend before he can progress to the next
