Our own documents

Cosmic Birth Map writes its own documents for what the old books could not know: the outer planets, the planetary cycles, the chart shapes and aspect figures, and the modern meanings of the houses, the angles and the planets. They are written from the works above; no author's text is reproduced in them.

Our readings draw on classical astrology, the English esoteric revival, Astrocábala and modern astrology. The interpretation of your chart is our own.
