注大乘入楞伽經 2.28

2.28

上句問：悉檀，此云義宗。下句問：世諦諸見。又，天台宗有四悉檀：一世界、二對治、三為人、四第一義。故云「若失四悉檀意，自行、化他皆名著法；若得四悉檀意，自他俱無著。」

The first line asks about siddhānta, which translates here as established tenets. The second line asks about the various views of conventional truth. Furthermore, the Tiantai school maintains four siddhāntas: first, the mundane; second, the therapeutic; third, the individual; and fourth, the ultimate truth. Hence it is said: "If one misses the intent of the four siddhāntas, both one's own practice and one's teaching of others are called clinging to dharmas; if one grasps the intent of the four siddhāntas, both self and other are free from clinging."
