2.210

心竟泯者。以聞法之時妄心不起，心既不起境即不生，心境兩亡故云泯也。此即不得以生滅心行聽實相法，此通依計，故皆泯也。斯則染心俗境一對。

"Mind is completely extinguished": because when hearing the Dharma no deluded thoughts arise, and since the mind does not arise, objective conditions are not produced. Mind and objects are both obliterated, hence it is said to be "extinguished." That is, one cannot listen to the teaching of dharmatā with a mind-activity of arising and ceasing; this applies generally to [both] paratantra and parikalpita, so both are extinguished. This constitutes the pair of defiled mind and worldly objects.
