法華義疏 8.77

8.77

「佛知是以」下，第二，明佛雖知理一，為物未堪昔不即說。此即顯眾生不知同也。

From 'The Buddha knows this' downward is the second [section], clarifying that although the Buddha knows that the principle is one, because beings were not yet capable [of it], he did not immediately preach it in the past. This reveals that sentient beings do not know the sameness.
