The point of Directional Strength is similar to that of Exaltation Strength. Just as planets have one sign position in which they are exalted, they have one house position in which they gain Directional Strength. A planet gets 60 points of strength at the place of full Directional Strength and 0 points at the place opposite it.
The intermediate positions are also divided by three. Each three degrees away from the place of Directional Strength causes a loss of one point of strength.Planets have Directional Strength in different directions.
