Wei Wu Wei goes on to say; "As long as "you" do anything as from a "you," You are in bondage.
The difference is between what you are and what you think you are but are not.
Here, Wei Wu Wei is referring to the error of identification with a pseudo-entity, an object furnished with autonomy and volition. Taking the reflection of the sun (to use last weeks theme), as the sun itself. Upon reducing the suns reflection (the pseudo-etinty), to itself it is found to be unsubstantial with no inherence whatsoever.
If in saying "I" as from a psycho-somatic phenomena that believes itself to be an independent entity acting or not-acting as a result of its own volition, then no matter what we may know or ignore, practise or not-practise, we are a cat chasing its tail and "no nearer to home then the day you were born."
