I always take an aspect between the ruling planets (i.e., the rulers of their Ascendants) as a testimony to the fact that the two people are likely to have a relationship of extraordinary intensity and importance… The close interaction of the ruling planets’ energies can be seen as indicative of a particularly specific symbol of how the two people interact with each other… in the vast majority of such cases, all of the other levels of interaction shown in a comparison will be secondary to the intense type of interchange symbolized by the aspect between the rulers.
