Earlier when [the Buddha] preached about the cause, the entrustment [of the sūtra] was made as well. Because the theme has not yet been wound up, there has been no separate chapter [for entrustment]. Here [the Buddha] now enunciates that both cause (Chapters 1-13) and effect (Chapters 14-21) have come to an end and that the preaching of li has been completed. As such, the great wisdom of the Thus Come One. Here he entrusts them to keep this sūtra, while striking [incalculable bodhisattva-mahāsattvas] on the crown of the head, to show that li is so deep and the worldly facts (shih) [involved as descriptive tools] are so sublime. This chapter is established for this purpose.
