Read a chart from structure to synthesis

Begin with accurate calculation. Then identify the Ascendant and chart ruler, Sun and Moon, emphasized houses, close aspects, and repeating element or modality themes.

A chart is not a stack of unrelated descriptions. Synthesis explains how several factors modify each other and which interpretation best matches the chart as a whole.

Frequently asked questions

What is the best way to explore astrology guides and chart education?

Why are the guides connected?
