大乘起信論略述 2.214

2.214

論。六者於如來境信得增長　述曰。謂本始覺名曰如來。修行所觀即名為境。修三昧者雖未契證。信此真如本無念也。

[Treatise:] Sixth, regarding the realm of the Tathāgata, faith increases. [Exposition:] Original and initial awakening are called the Tathāgata; what is contemplated in practice is called the realm. Although one who cultivates samādhi has not yet realized it, they believe that this suchness originally has no stirring thought.
