仁王經疏 3.229

3.229

釋曰：自下第二別釋六種方便。即分為六，皆有二段：先牒、後釋。此釋第一實相方便。緣第一義故名實相，起巧功能名為方便。

Explanation: Next, the second [part] specifically explains the six kinds of expedient means. It is divided into six, each having two sections: first repeating [the sūtra's words], and then explaining them. This explains the first, the expedient means of the true mark. Taking the paramārtha-satya as its object, it is called 'true mark'; producing skillful functioning, it is called 'expedient means.'
