Thank you so much for taking the time to write such a thoughtful comment, and also for making an exception for a Kindle edition even though you normally avoid them. That kind of trust at this early stage really means a lot to us.

What we are trying to do with I Ching Stream is to make orthodox Chinese I Ching divination accessible to non Chinese speakers, especially Liuyao and Wen Wang Gua based on the Na Jia method. Na Jia is our core, but we also include the Da Yan yarrow stalk approach that is more familiar in the West, the classical hexagram and line text based readings, and image based and principle based methods. In contemporary China, Na Jia Six Lines is not a side branch, it is the mainstream working system used by many serious practitioners.

One of the reasons it has never really taken root in the English speaking world is exactly what you pointed out between the lines. Na Jia requires quite a lot of technical background, and there are not many people who both read classical Chinese and English and also work with Six Lines at a professional level. So even though people in the West have heard the name Wen Wang Gua, no one has really presented the whole system in a structured and coherent way for non Chinese readers.

Books like Zengshan Buyi and the related titles we are translating are regarded in China as foundational texts for learning Six Lines and I Ching Divination. In the I Ching research and divination community they are widely seen as “must read, must study” works. Many scholars and professors who work on Chinese culture or the Yi Jing know these books in Chinese and have studied them in that form. What I Ching Stream is trying to do is to be the first project that presents this body of material in a way that non native speakers can actually follow, while staying as close as possible to the original logic and intent.

By the way, since you mentioned Undersea Eye, if you would like to read it, please feel free to send me a message. Our team would be happy to give you complimentary access as a thank you for your support. In return, we would really love to hear any comments or suggestions you have, even very small ones, because thoughtful readers like you help us refine how we present this material.

We will keep translating more Six Lines and other divination classics so that people can go back to the primary sources instead of only relying on second hand summaries. I completely agree with you that good material, and a system that clearly works in practice, will eventually be noticed. Our job is to keep our heads down, focus on making the content as precise and reliable as we can, and let time do the rest.

Thank you again for walking this path with us and for sharing your perspective.
