華嚴經探玄記 6.10

6.10

第二放光中，足指是光出處。但足指有行、住二力，前彰住、此顯行，故別也。餘同前釋。

In the second [part], on emitting light, the toes are the place where the light emerges. But the toes possess the two powers of walking and standing still; the former revealed standing still, while this reveals walking, hence they differ. The rest is the same as the previous explanation.
