Astrology
Learn to read an astrological chart
Astrology uses celestial positions for symbolic interpretation. Begin with the chart itself: find a planet, read its sign and house, then measure an aspect.
Start with the first chart reading
From the first placement to a transit reading
These six lessons use the same constructed positions, so you can follow one example across the chart, houses and aspects. Choose the subject you need or read them in order.
