淨名經關中釋抄 1.26

1.26

菩薩無心者。非石木之無心也。直以凡夫取相分別心說故名有心。菩薩常觀無相無分別心。而方便應物假名相說。故名無心。

"A bodhisattva has no mind": this does not mean being mindless like stone or wood. It is simply that because ordinary persons possess a discriminating mind that grasps signs, they are said to have a mind. A bodhisattva constantly contemplates the signless, non-discriminating mind, yet through skillful means responds to beings and speaks in conventional terms and signs; therefore, he is said to have no mind.
