The planeis may cause a good or bad yoga when they are within an orb of twelve degrees. Of these two, if the planet that has a slower average motion is in advance and the one that has a faster average motion is behind, the yoga yields results. The effects are fully realised when they are within one degree, and they are absent when they are separated by twelve degrees. In the intermediate positions we have to determine the strength of the yoga proportionately. lf the faster planet is in advance by twelve or more degrees, the good effects of the yoga are spoilt till that period.
