True thusness is without defiling thought; it cannot be known through conception and thought.

真“是”是无偏颇；是无法以、观念来颖悟。

True thusness is the substance of thought and thought is t he function of true thusness. To think of thusness, to define it in thought is to defile it.

真“是”是质，而是真“是”机构，及“是”，要固定义它犹亵渎它。
