Fourth, the benefit of subsuming the stages means that each of the five stages, such as faith and so on, subsumes all stages. However, there are two approaches: 1. the approach wherein the stages are wholly identical, in that all stages are a single stage, and thus upon the fulfillment of the ten faiths one immediately realizes Buddhahood; 2. the approach wherein the stages mutually assist, in that a single stage contains all stages within it, just as the ten abodes and up to the ten grounds are present within the ten faiths, as explained in the "Chapter on Bhadraśrī." That each of the ten abodes and so forth subsumes the various stages, both possessing the two approaches, is as explained at the place of the monk Sāgaradhvaja and in the "Chapter on the Ten Abodes" and so on. It also says: "Abiding in a single ground, one universally subsumes the merits of all grounds." All the other qualities—the unobstructedness of breadth and narrowness, up to Indra's net—are also fully present, which can be understood by considering by analogy.
