Brian Luke Seaward in his book Stand Like Mountain, Move Like Water, said: “To see the entire picture, we must remember that creating a space is essential for acquiring new insights.” He includes a quote from Lao Tzu in the Tao Te Ching:
“Thirty spokes share the centre of one wheel;
Consider that the hole of the centre is essential to wheel’s function.
Craft a pot from earthen clay;
Consider that the space inside provides the pot’s true function.
Cut a hole in the wall to make both window and door;
Consider that the space within four walls is essential for living.
Understand that the form and structure is most beneficial;
Consider also that the empty space within the form is most useful.”
