Chatpter 11 of Tao Te Ching speaks to substance and emptiness, that one cannot exist without the other. Thus it has been written that the Tao embeds everything because the Tao is emptiness.
I can certainly speak to the practice of emptiness or silence allowing for realizations or growth that could not have come before, so in that way the Tao does allow for functionality within my own life, or any other followers I guess.
As always I owe much of my insights to Derek Lin’s Tao Te Ching Annotated and Explained.
Thirty spoke join in one hub
In its emptiness, there is the function of a vehicle
Mix clay to create a container
In its emptiness, there is the function of a container
Cut open doors and windows to create a room
In its emptiness, there is the function of a room
Therefore, that which exists is used to create benefit
That which is empty is used to create functionality
