Yoshiro Tamura, "Introduction to the Lotus Sutra", p96-97In chapter 21, the bodhisattvas, centering around Superior Practice Bodhisattva, are given the mission to propagate the Dharma (the “special entrustment”), and in chapter 22 this is extended to all the bodhisattvas (the general entrustment”). Those so entrusted make vows to dedicate themselves to following the Buddha’s orders and to working to embody the truth. “We will respectfully do all that the World-Honored One has commanded. Please, World-Honored One, do not worry about that.” A very similar vow can be seen in chapter 13.
When the Buddha’s entrustment orders were completed, the stage of the drama returned from the air to Mt. Gṛdhrakūṭa on the ground, and those who received the mission distributed themselves around the Sahā world. The main story line of the Lotus Sutra ends here. The remaining six chapters are supplemental, yet the merits and efficacy of faith are emphasized and taught in various distinct ways in them. Thus, these chapters came to be highly regarded among the people.
