With BLENDINGS, Amir Bey has published his latest findings on relationship analysis. Over the years, in his search to understand his own relationships, Amir has developed a unique method for gaining perspective on social interactions. His research has led him to discover how the compatibility and parallels between Composite and Davison Relationship Charts can lead to surprising insights.
The Davison method has few treatments by astrologers beyond the British astrologer Ronald Davison in his Synastry, Understanding Human Relations through Astrology. BLENDINGS is one of the few, if not the only, recent literature on the method, and the only one that compares and combines the two methods.
Through this research, he has discovered that the MC, Sun, and True North Node of the Composite and Davison charts are always within 5º of conjunction or opposition of each other, rarely more than 4º. From this he recognized what he called the Triad of relationships. This led him to create and research what he calls The Part of Union, whereby the arc between the Sun and True North Node is projected from the MC clockwise. The formula would be the MC + True North Node − the Sun.
This point is also a measurement of the Sun/Nodal axis—the eclipse cycle. It not only can be used for relationships, but gives insight for a person’s relationship capacity, as well as mundane study. This consistency of these three points shows how identity, purpose, and life direction are important components of relationships.
An important difference and parallel between Composites and Davisons is that the Composite chart’s planets and points are calculated through their midpoints, with the MC as the anchor for the houses. The Davison is calculated through the midpoints of the two entities’ birth times and geographical locations. This allows the Davison to behave like a natal chart, enabling the calculation of relationship solar returns, progressions, planetary lines, and other cyclic measurements more accurately than the Composite.
Amir maintains that both methods should be used together for a complete view of a relationship.
Most software today offers both methods. Some programs do not calculate the Composite correctly, using the Ascendant rather than the MC as the house anchor.
