大乘義章 9.49

9.49

第一門中約就行位辨定先後。二種性者，一習種性、二性種性。此二種性若據位分，習種在前、性種在後。若就行論，性習同時，以同時故前後不定。依體起用，先明性種、後明習種；尋用取體，先明習種、後明性種。與彼證道、教道相似。就位以論，教道在前、證道在後。世間之行為教道故，所以在前；地上之行為證道故，所以在後。據行論之，證教同時，以同時故先後不定。依體取用，先證後教；尋用取體，先教後證。先後如是。

In the first gate, the sequence is clarified and determined with respect to practice and stage. As for the two kinds of gotra: first, the gotra of habit (adhimukti-gotra / vāsanā-gotra); second, the gotra of nature (prakṛti-gotra). If these two kinds of gotra are divided according to stages, the gotra of habit is prior and the gotra of nature is posterior. If discussed according to practice, nature and habit are simultaneous; because they are simultaneous, priority and posteriority are not fixed. Arising function relying on essence, one first clarifies the gotra of nature and later clarifies the gotra of habit; tracing function to grasp essence, one first clarifies the gotra of habit and later clarifies the gotra of nature. This is similar to the path of realization and the path of teaching. Discussed in terms of stages, the path of teaching is prior and the path of realization is posterior. Because the practices of the mundane world are the path of teaching, they are therefore prior; because the practices on the stages are the path of realization, they are therefore posterior. Discussing it based on practice, realization and teaching are simultaneous; because they are simultaneous, priority and posteriority are not fixed. Grasping function relying on essence, realization comes first and teaching later; tracing function to grasp essence, teaching comes first and realization later. Such is their sequence.
