大方廣佛華嚴經疏 6.13

6.13

八普往十方等者，即無相解脫門也。雖身應十方，寂然不動智宣諸法，怕爾無依不取於相，如如不動故。

Eighth, "universally going to the ten directions, etc.," is the signless liberation gate. Although the body responds to the ten directions, it remains still and unmoved while wisdom proclaims all dharmas; tranquil and without reliance, it does not grasp at marks, because it is unmoving like tathatā.
