The guided path
One lesson at a time.
Six stages, from the first distinctions to deeper study. Start at the beginning or pick up where you feel ready.
Stage 1 · 6 lessonsEnter the languageSeparate planets, signs, houses, and aspects before interpreting.
Put it into practice. Return to the example in Start here. Name its planet, sign, and house, then explain why a second position is needed to identify an aspect.
Explore the sky
After the foundations, explore how the same vocabulary is used for the Moon's phases and the Sun entering Aries.

Put it into practice. Combine one annual topic, one current transit, and one lunar cue.
