Zuowang is allowing everything to slip from the mind, not dwelling on thoughts, allowing them to come and go, simply being at rest… Just remain empty and there is no separation from Dao… Do not think too much about the theory of this, otherwise you are sure to disturb the mind. It is like the sun rising in the east and setting in the west. To think about stopping it halfway is a futile exercise. Just trust the inherent natural process.
