華嚴經探玄記 3.13

3.13

第六四種道理者，《雜集》第十一「因辨觀察契經等法，應當解釋諸法道理。道理有四：一觀待道理、二作用道理、三證成道理、四法爾道理。」案云：觀待有二。一俗諦緣起要相待生，因此通染淨。二真諦之理待了因顯，此唯約淨。二作用亦二：一緣起諸法各有業用、二真如法界依持等用。三證成亦二：一比量成立、二現量成立。四法爾亦二：一諸緣起法有佛無佛性從緣起、二真如法界性自平等。

Sixth, as for the four kinds of principles: Fascicle eleven of the Samuccaya states: 'In connection with discerning and examining the teachings such as sūtras, one should explain the principles of dharmas. There are four principles: first, the principle of dependence; second, the principle of function; third, the principle of demonstration; and fourth, the principle of dharmatā.' I note: Dependence has two [aspects]: first, dependent origination in conventional truth necessarily arises in mutual dependence, and through this it extends through both defilement and purity; second, the principle of ultimate truth depends upon revealing causes to be disclosed, and this is solely in terms of purity. Second, function also has two: first, all dependently arisen dharmas each have their karmic function; second, the tathatā-dharmadhātu has functions such as support and maintenance. Third, demonstration also has two: first, establishment through inference; second, establishment through direct perception. Fourth, dharmatā also has two: first, whether Buddhas exist or do not exist, the nature of all dependently arisen dharmas arises from conditions; second, the tathatā-dharmadhātu is by its nature self-equal.
