Strength of aspects

The relative strength of aspects is a debatable factor, for so much depends on the intrinsic character of the rays. If you consider the rays as energy, each altered in character by virtue of the sign position of the planet from which it is emitted, the aspect determines the direction of the influence upon you as an individual. It is in the synthesis of qualitative, quantitative and directional factors that the practice of Astrology becomes both an art and a science.
