If you also use Midpoints and I find them very useful, especially when considering events rather than traits, the amount of information poured at the hapless astrologer is beyond handling. This would only happen if I knew enough about the individual already for me to consider it warranted. I use only the first 12 harmonics, i.e., the Overt and Potential aspects, unless the native is also undergoing depth analysis of some kind. I pay regard only to those midpoints where all three of the aspects involved are on the same harmonic, using all 36 harmonic aspect series. This means that the midpoint has to be very close to exact for it to be considered.
Every planet is in aspect to every other planet.
Aspects become stronger as they approach exact. Their strength varies inversely as the square of the percentage of the distance of the planet from exactitude. This material may not be copied or passed on without permission having been given and due acknowledgment of its source.
