四明十義書 2.91

2.91

故《輔行》云：聖人變化所造，亦令眾生變心所見。此文雖屬心法變造，今引因證果也。又《般舟》云：約三十二相為境，修乎三觀，顯乎三諦。故應佛色心既為行者所觀，乃是感應共造，故約感邊亦得是外陰入法也。豈非觀妄顯真耶？是故等覺猶見他佛，唯至妙覺更無彼此色相迭相見故。

Therefore, the Fuxing states: 'What is created through the transformations of the holy ones is also caused to be seen through the transformations of sentient beings' minds.' Although this passage pertains to transformation and creation by the mental factor, it is cited here to verify the effect by means of the cause. Furthermore, the Pratyutpanna-[samādhi-sūtra] states: 'Taking the thirty-two marks as the object, cultivate the threefold contemplation and reveal the threefold truth.' Therefore, since the form and mind of the response Buddha are the object contemplated by the practitioner, they are co-created through resonance and response (ganying). Thus, in terms of the resonant aspect, they also constitute external phenomena of the aggregates and sense bases. Is this not contemplating the deluded to reveal the true? For this reason, those of equal awakening still see other Buddhas, whereas only upon reaching wondrous awakening is there no longer mutual seeing of forms between this and that.
