妙法蓮華經玄義 5.141

5.141

今通用四悉檀，歷十法，論妙，不妙；具說三軌，共成大乘。大乘之中，備有三法及一切法，不相混亂，即是世界悉檀。資成資發智慧，以生善故，是為人悉檀。觀照破惑，諸惡滅故，是對治悉檀。真性實理，為第一義悉檀。一段眾生，宜以大乘名說，得四利益也。

Now, generally employing the four siddhāntas, we trace them through the ten dharmas to discuss what is subtle and what is not subtle. Fully expounding the three tracks, they together constitute the Great Vehicle. Within the Great Vehicle, the three dharmas and all dharmas are fully present without confusing one another; this is the worldly siddhānta. The auxiliary supporting and instigating wisdom so that good is produced is the individual siddhānta. Contemplation and illumination destroying delusion so that all evils are eliminated is the diagnostic siddhānta. The true nature and real principle is the paramārtha siddhānta. For a section of sentient beings, it is fitting to teach under the name of the Great Vehicle, and they obtain the four benefits.
