Wu Hsin repeatedly returns to three key points. First, on the phenomenal plane, when one ceases to resist What-Is and becomes more in harmony with It, one attains a state of Ming, or clear seeing. Having arrived at this point, all action becomes wei wu wei, or action without action (non-forcing) and there is a working in harmony with What-Is to accomplish what is required. Second, as the clear seeing deepens (what he refers to as the opening of the great gate), the understanding arises that there is no one doing anything and that there is only the One doing everything through the many and diverse objective phenomena which serve as Its instruments. From this flows the third and last: the seemingly separate me is a misapprehension, created by the mind which divides everything into pseudo-subject (me) and object (the world outside of this me). This seeming two-ness (dva in Sanskrit, duo in Latin, dual in English), this feeling of being separate and apart, is the root cause of unhappiness.
Wu Hsin is a pseudonym of Roy Melvyn. Although Melvyn presents himself as the "translator" of the supposedly lost writings of Wu Hsin, the character is in reality entirely fictional.
According to his biography, Wu Hsin was a Chinese sage who lived about one hundred years after Confucius, some time between 403 and 221 BCE. His name translates to "no mind", alluding to an important concept of non-duality in Daoism as well as Zen Buddhism.
I have been on the non-dual path for over 30 years. This book is the best I have ever found and I have looked extensively in all non-dual traditions. I love that it is Taoist as I have been a tai chi teacher for 30+ years. Reading Wu Hsin feels like "going home" to me ~ bringing me a sense of ease of being, well-being, natural buoyancy, being in the present moment, and experiencing exquisite clarity, a silent mind, a still heart, freedom in my breath.
This thing is so freaking amazing, I cannot explain it. Every word in this book carries so much truth in it that my soul sings when it hears them. This is a book that I've flipped through, so I need to sit down and read it fully from beginning to end one day. This book is just so enlightening and peace-bringing. Definitely a favourite.
