A friend of mine wants me to track this muther down, he's desparate, it seems.
A Chinese version is OK but there are a few English translations. The Derek Walters translation is out of print now, so I hear.
Its name translates as "Canon of Supreme Mystery" It's an obscure relative of the I Ching, the book of changes, written in 2 BCE. Confucius refers to it in his writings, but the TXJ nearly been written out of history.
It's unlikely in the extreme that anyone can help, but any faint leads are appreciated. I'm willing to order from outside Kunming if necessary.
