The Hindu Book of Astrology, dating to the dawn of the 20th century, is actually a Western Zodiac system associated with the East-to-West craze of its own era. Originally containing various advertisements, it is a good work; one which is no less authentic in its mysticism than any grimoire associated with Solomon or alchemical work bearing the name Agrippa or Hermes. It covers the basic tenets of the twelve signs, their associations, and their meaning, as well as a fairly lengthy expose on each cusp sign. It then admonishes the reader to study the occult.
