妙法蓮華經玄贊 7.162

7.162

贊曰：此結佛知、眾生不知。「地」謂種子，或是心等行相體性總名為地。不同前地，彼謂一真。彼說佛教，名為一雨。一真法界，名為一地。其中四生，名卉木等。三乘五乘、有性無性，佛悉知之，眾生不知。

The commentary says: This concludes that the Buddha knows while sentient beings do not know. "Ground" refers to seeds, or the active aspects, substances, and natures of minds and so forth are collectively termed the ground. It is not like the ground mentioned before, which meant the single reality. There, the Buddha's teaching was called the single rain, and the single true realm of reality (dharmadhātu) was called the single ground. The four kinds of birth within it were called the plants and trees, etc. As for the three vehicles and five vehicles, those with gotra and those without gotra, the Buddha fully knows them, but sentient beings do not know.
