大方廣佛華嚴經疏 20.5

20.5

三宗趣者，明法不同略有四種，謂教、理、行、果。尋教悟理，觀理起行，行成得果，皆初宗後趣。又此四皆宗，為成後位及成勝德為趣。

Third, as for the central theme and purpose: illuminating the Dharma differs, having briefly four kinds, namely: teaching, noumenon, practice, and fruit. Tracing the teaching to awaken to the noumenon, observing the noumenon to give rise to practice, and practice being completed to attain the fruit—in all cases, the former is the central theme and the latter is the purpose. Furthermore, all four of these are the central theme, while accomplishing the subsequent stations and accomplishing superior virtues constitute the purpose.
