大乘起信論義疏 1.48

1.48

自下第七總結。「當知一切法不可說不可念」者，就妄法中言說心念皆不相應也。此明真如體竟也。

From here below, the seventh [topic] generally concludes. "It should be known that all dharmas cannot be spoken of and cannot be thought of": in terms of delusive dharmas, neither spoken explanations nor mental thoughts are in accord [with it]. This concludes the explanation of the essence of tathatā.
