6.174

非如言說知者，以真如法離言說故，但是真智之境，唯證相應，故云自證。第一第七第十七及此一段，皆云不以相見如來者，義意皆別。初以對果疑因，次明感果離相，次說依真現假，後明約假求真，故不同也。

"Cannot be known through verbal explanation": because the phenomenon of tathatā transcends verbal explanation, it is solely the realm of true cognition and corresponds only to personal realization; hence it is called self-realization. The first, seventh, seventeenth, and this section all state that one does not see the Tathāgata through marks, but their meanings and intents are distinct. The first doubted the cause in relation to the fruit; the next clarified that evoking the fruit transcends marks; the next explained that the provisional is manifested based on the real; the latter clarified that one seeks the real by relying on the provisional; hence they are not the same.
