The merits of the person who causes even a single man to go and hear the Dharma are so many. It is needless to speak of the merits of the person who hears [this sūtra] with all his heart, reads it, recites it, expounds it to the great multitude, and acts according to its teachings.

This refers to the forthcoming chapter. What has not been substantiated in the preceding, and what has so far been omitted, is how much merit there will be for those who rejoice appropriately, “explaining” by turns and propagating [the sūtra to others].
