法華義疏 2.172

2.172

「種種因緣」下，第三、明說教意也。上半序佛說教，說教有二：一法，二喻。下半明佛說教意，佛說教意亦有二種：一者上弘，二者下利。據佛而言者，教能顯理如燈照明，理是所詮稱為佛法，開悟眾生者謂下利也。一切眾生悉有佛性，以無明為扉、邪疑為關故不悟佛性，諸佛扸邪疑關、開無明扉，令見佛性，故稱悟也。

From 'Through various causes and conditions' downward is the third part: clarifying the intent of preaching the teaching. The first half introduces the Buddha's preaching of the teaching, which has two aspects: first, the doctrine; second, parables. The second half clarifies the Buddha's intent in preaching the teaching, which also has two kinds: first, upwardly propagating; second, downwardly benefiting. Stated from the Buddha's perspective, the teaching can illuminate the principle like a lamp giving light; the principle is what is expressed and is called the Buddha-dharma. Awakening sentient beings refers to downwardly benefiting. All sentient beings possess buddha-nature; having ignorance as doors and deviant doubts as bolts, they do not awaken to buddha-nature. The buddhas break the bolts of deviant doubt and open the doors of ignorance, enabling them to see buddha-nature; hence it is called 'awakening'.
