There are some books you read through and others that you not only read, but return to, time and time again. The Eastern Mysteries (previously published as The Key of it All—Book 1: The Eastern Mysteries) by David Allen Hulse will be such a book for you.
One of the most important creations in human history is language. Within the letters and words of virtually every culture, there have been hidden mysteries and magick. In The Eastern Mysteries you will find the occult keys to Cuneiform, Hebrew, Chinese, Arabic, Sanskrit, and Tibetan languages.
Each self-contained section can be read as a separate work. Each secret tradition revealed parallels the others. Extensive cross-references allow you to contrast and compare the mystical and magical beliefs of the ancient cultures.
You'll find the entire text of the famous I Ching, along with meanings of the symbols and how to do readings. The 231 Gates of the Sepher Yetzira are fully described, including their relationships to astrology and the Tarot. This just barely hints at the massive amount of information in The Eastern Mysteries. No matter what system you follow, you will consult this book again and again. Get your copy today.
