I have been studying the relation between the I Ching and Sabian symbols for about ten years. The research started when I was around 20 years old. At that time, I had already studied astrology and I Ching for about two years. However, I lacked practical experience and knowledge about it yet. Therefore, it was only one method that I understood the relation between 64 hexagrams and Sabian symbols. It links "Zodiac signs(12 constellations)" and "Earler Heaven Bagua". About a year after that, I noticed another perspective. I understood it in an intuitive way during practice of "Kimon Tonkou". "Kimon Tonkou(Qi Men Dun Jia)" is a technology that uses nine spaces where complex elements are included. In that experience, I obtained a new viewpoint that connected astrology with the I Ching. That viewpoint linked "Later Heaven Bagua(King Wen sequence)" and "Zodiac signs". Afterwards, I found the third viewpoint in 2004. This can arrange one degree to one hexagram's Horizontal Line. By these findings, I now can interpret the I Ching multilaterally. Current study results are in my website. http://ciarchives.nemachinotsuki.com/i-ching_sabian.html However, my website is written in Japanese, so I made two English versions.
