1.109

六識界者，若根、塵相對即有識生。識以識別為義，識依於根，能識別於塵，故此六通名識也。若了識從緣生，豈計有神？使知謬取也。

Regarding the six consciousness dhātus: when sense faculties and sense objects face each other, consciousness arises. Consciousness has the meaning of discerning; consciousness relies on the faculty and is able to discern the sense object; hence these six are universally called consciousness. If one realizes that consciousness arises from conditions, how could one reckon there to be a soul? This causes one to know the fallacy of grasping [such a view].
