When people do not ignore what they should ignore, but ignore what they should not ignore, this is known as ignorance.
ZhuangziThus, those who say they would have right without its correlate, wrong; or good government without its correlate, misrule, do not apprehend the great principles of the universe, nor the nature of all creation.
ZhuangziWhen the shoe fits, the foot is forgotten; when the belt fits, the belly is forgotten; when the heart is right, "for" and "against" are forgotten. There is no change in what is inside, no following what is outside, when the adjustment to events is comfortable. One begins with what is comfortable and never experiences what is uncomfortable, when one knows the comfort of forgetting what is comfortable.
