What astrological harmonics tell

John Sandbach

How To Use Harmonics explains the meaning of various harmonic charts that can be astrologically generated. The book focuses on the first 13 harmonics, giving meaning for the planets in each one of these charts. There are very few books that have been written on this subject.

According to Indian Astrology the most important harmonic chart is the 9th, which shows the direction in which the person is headed in this lifetime. This is a key chart to explore to understand the Nodes better and to help a person understand the path of their own personal evolution.
