2.25

The second section is the explanation. "Without shape" means without appearance. "Without name" means without appellation. "The sage is spiritual through it": "through" means "uses." The sage uses this spiritual penetration so that there is nothing he does not know. "The sage is empty through it, so being empty, he does not lose illumination": Although empty, he does not lose the function of illuminating contemplation. "Being without shape and without name, his illumination does not lose emptiness": Although illuminating and knowing, he does not grasp at characteristics. "Blending without changing": *hun* means blending; *yu* means changing. This comes from Du Yu's commentary on the *Chunqiu*. Although blended together with the myriad phenomena, they each remain distinct and do not change. "Moving to engage the coarse": Making movements to respond to circumstances is called "engaging the coarse."
From "Therefore, the functioning of sacred wisdom": It always has function and is never interrupted even for a moment, yet seeking its form is never possible even for an instant.
