Wisdom is like water. It resides in the lower meditation field, the belly. The head is for thinking; the heart for willing and desiring. The belly is the place for wisdom and contemplation. We ‘return’ to Dao’s gestating presence from this inner womb of intuitive awareness.

—Master Zhuang (quoted in Michael Saso: The Teachings of Daoist Master Zhuang, Oracle Bones Press, 2012)
