The skilled craftsman knows that you must have the right tool for the right job and he never blames his tools for any projects with shortcomings. The skilled practitioner of the Dao knows that there is a time for yin and a time for yang. One size does not fit all. There is a time for everything and a time for nothing. To know when to use one over the other, or both in unison demonstrates that you have learned. The Tao Te Ching is the tool you need. It would be most wise to learn how to use it.
