問：何以明脫而為道諦？答：三明具有正助二道，無漏正也、過未助也。道諦不出正助之行。又可三明正也、八解助也。又八解者，若於事禪達實相理而能化用，實理正也、化用助也。於如是等，方名道諦。

Question: Why are the [three] clarities and [eight] liberations taken as the truth of the path? Answer: The three clarities fully possess both the direct and auxiliary paths: the undefiled is direct, while the past and future are auxiliary. The truth of the path does not exceed direct and auxiliary practices. Alternatively, the three clarities are direct, and the eight liberations are auxiliary. Furthermore, regarding the eight liberations: if one penetrates the principle of true reality within phenomenal dhyānas and can apply it for transformation, true principle is direct, and transformative application is auxiliary. Only when regarding such [practices] is it called the truth of the path.
