次就解行以分四位。於中有二：一解行參論、二解行并說。言參論者，此四位中分為兩對，前二一對先解後行，後二一對先解後行。相狀如何？習種位中成就教解，故《華嚴》云「十住菩薩隨所聞法，即自開解，不由他悟。性種位中，隨起教行。」故《華嚴》中說為十行。初對如是。第二對中，初解行住，修習理解，是故經中說為解行，解為行故。又《地經》中說彼解行為觀分明。觀猶解也。初地已上，成就理行，故論名為行方便持。據此以論，習種解行解觀成就，性種十地行德成也。言并說者，聞思修證四種之中，聞思是解、修證是行。習種位中，依教生解，成就聞慧。性種位中，依義生解，成就思慧。解行位中，依教起行，成就修慧。初地已上，依理成行，成就實證。解行相對，分別如是。上來四門，合為第二就位分別。

Next, the four stages are distinguished in terms of understanding and practice. Within this there are two [approaches]: first, discussing understanding and practice correlatively; second, stating understanding and practice together. As for discussing them correlatively: these four stages are divided into two pairs; the first two form one pair with understanding first and practice second, and the latter two form one pair with understanding first and practice second. What are their characteristics? In the stage of the lineage of habituation, doctrinal understanding is perfected; thus the Huayan jing says: 'Bodhisattvas of the ten abidings, in accordance with the Dharma they hear, immediately open up understanding on their own without relying on awakening through others.' In the stage of the natural lineage, one undertakes practices in accordance with the teaching; therefore the Huayan jing speaks of them as the ten practices. Such is the first pair. In the second pair, first, in the abiding of understanding-and-practice, one cultivates understanding of principle; therefore the sūtra speaks of it as 'understanding-and-practice' because understanding serves as practice. Furthermore, the Di jing states that this understanding-and-practice is clear contemplation; contemplation is equivalent to understanding. From the first ground onward, practice of principle is perfected; therefore the treatise names it 'upholding the skilful means of practice'. Discussing it on this basis: in the lineage of habituation and understanding-and-practice, understanding and contemplation are perfected; in the natural lineage and the ten grounds, active virtues are perfected. As for stating them together: among the four kinds—hearing, thinking, cultivating, and realizing—hearing and thinking are understanding, while cultivating and realizing are practice. In the stage of the lineage of habituation, relying on the teaching generates understanding, perfecting the wisdom born of hearing. In the stage of the natural lineage, relying on the meaning generates understanding, perfecting the wisdom born of thinking. In the stage of understanding-and-practice, relying on the teaching initiates practice, perfecting the wisdom born of cultivation. From the first ground onward, relying on principle perfects practice, perfecting true realization. Such is the distinction made in correlating understanding and practice. The above four sections together constitute the second [part], distinguishing with respect to stages.
