The explication of the idea that the cause of three turns out to be the cause of One is to be completed here. In the chapter preceding the present one, it has been explained that the great beings (mahāsattvas) will propagate this sūtra and that the ranks of voice hearers also will propagate this Dharma “in other lands.” Among these are those who wish to transmit this sūtra but do not know how to do it. [The Buddha] therefore sets up this chapter to teach them the practical modus operandi.

“A Bodhisattva-mahāsattvas who wishes to expound this sūtra in the evil world after [my extinction] should practice four sets of things {dwell securely in four dharmas}.

If one is able to “dwell securely in four dharmas,” then the body becomes tranquil and the spirit is settled. When the spirit is settled and the body tranquil, then external suffering does not interfere with them (the four dharmas). When external suffering does not interfere with them, one can be said to be “comfortable.” Because they are then able to preach the Dharma tirelessly, beings receive its benefits, “The four dharmas” are as follows: The first dharma consists of the acts of dwelling and the acts of the two kinds of places “that [the bodhisattva-mahāsattva] approaches with familiarity.” “The place that he approaches with familiarity” enables them to keep a distance from evils and remain close to li. As the mind rests on li, body and mouth do not commit any faults. Body and mouth not committing any faults constitute the second dharma. The third one is the state of feeling no jealousy. The fourth one is the state of feeling Great Compassion. As the three kinds of acts are purified, compassionate thought also pervades their minds. Is not the propagation of the Dharma in this way also great?
