This beautiful quote from Lao Tzu reminds us of the importance of both substance and space, matter and energy, the visible and the invisible. Sometimes what we can’t see or perceive is of equal or greater importance than what we can see and perceive. Try to create that space and emptiness within you and see what happens!
Thirty spokes end in a hub,
but it is the hole in the hub
that makes the wheel usable.
Vessels are shaped by kneading clay,
but it is the empty space inside that makes them useful.
Walls, penetrated by windows and doors, form rooms,
but it is the emptiness of the room that makes it useful.
Thus the material provides a potential,
but the immaterial provides the value.
