2.276

先可依二諦之境楷定聖心。若言心一者，假令權智應動觀物之時，為唯照物空無相邪？為照俗動有相邪？若覩下，出違。若觀相撫會，定失無相。若唯見無相，却失撫會也。聖心唯一，定應得一失一；若令二諦俱得，理合權實兩殊。

First, one can definitively determine the sage mind according to the realms of the two truths. If one says the mind is one, supposing that when upāya-jñāna responds in activity and observes things, does it solely illuminate the emptiness and animitta of things? Or does it illuminate conventional activity with characteristics? From 'If it beholds' onward, he reveals the contradiction. If it observes characteristics and adapts to encounters, it definitely loses animitta. If it only sees animitta, it conversely loses adapting to encounters. If the sage mind is only one, it definitely must gain one and lose the other; if one makes it attain both truths, in principle upāya and tattva must be two distinct things.
