It's about those who are able to convert others to the Lotus of the Wondrous Law, which, again, Hakuin reads as resolution of the Great Matter, not the literal text of the Lotus Sutra. It appears anti-climactic after the "Kwan Yin" sub-sutra mentioned below.
Chapter 26 is sufficient, I think, to get the flavor of both chapters:
Thereupon the Bodhisattva Mahâsattva Samantabhadra, in the east, surrounded and followed by Bodhisattvas Mahâsattvas surpassing all calculation, amid the stirring of fields, a rain of lotuses, the playing of hundred thousands of myriads of kotis of musical instruments, proceeded with the great pomp of a Bodhisattva, the great display of transformations proper to a Bodhisattva, the great magnificence of a Bodhisattva, the great power of a Bodhisattva, the great lustre of a glorious Bodhisattva, the great stately march of a Bodhisattva, the great miraculous display of a Bodhisattva, a great phantasmagorical sight of gods, Nâgas, goblins, Gandharvas, demons, Garudas, Kinnaras, great serpents, men, and beings not human, who, produced by his magic, surrounded and followed him; Samantabhadra, then, the Bodhisattva, amid such inconceivable miracles worked by magic, arrived at this Saha-world. He went up to the place of the Lord on the Gridhrakûta, the king of mountains, and on approaching he humbly saluted the Lord's feet, made seven circumambulations from left to right, and said to the Lord: I have come hither, O Lord, from the field of the Lord Ratnategobhyudgata, the Tathâgata, &c., as I am aware, Lord, that here in the Saha-world is taught the Dharmaparyâya of the Lotus of the True Law, to hear which from the mouth of the Lord Sâkyamuni I have come accompanied by these hundred thousands of Bodhisattvas Mahâsattvas. May the Lord deign to expound, in extension, this Dharmaparyâya of the Lotus of the True Law to these Bodhisattvas Mahâsattvas. So addressed, the Lord said to the Bodhisattva Mahâsattva Samantabhadra: These Bodhisattvas, young man of good family, are, indeed, quick of understanding, but this is the Dharmaparyâya of the Lotus of the True Law, that is to say, an unmixed truth. The Bodhisattvas exclaimed: Indeed Lord; indeed, Sugata. Then in order to confirm, in the Dharmaparyâya of the Lotus of the True Law, the females among the monks, nuns, and lay devotees assembled at the gathering, the Lord again spoke to the Bodhisattva Mahâsattva Samantabhadra: This Dharmaparyâya of the Lotus of the True Law, young man of good family, shall be entrusted to a female if she be possessed of four requisites, to wit: she shall stand under the superintendence of the Lords Buddhas; she shall have planted good roots; she shall keep steadily to the mass of disciplinary regulations; she shall, in order to save creatures, have the thoughts fixed on supreme and perfect enlightenment. These are the four requisites, young man of good family, a female must be possessed of, to whom this Dharmaparyâya of the Lotus of the True Law is to be entrusted.
Then the Bodhisattva Mahâsattva Samantabhadra said to the Lord: At the end of time, at the end of the period, in the second half of the millennium, I will protect the monks who keep this Satrânta; I will take care of their safety, avert blows [or punishment], and destroy poison, so that no one laying snares for those preachers may surprise them, neither Mâra the Evil One, nor the sons of Mâra, the angels called Mârakâyikas, the daughters of Mâra, the followers of Mâra, and all other servitors to Mâra; that no gods, goblins, ghosts, imps, wizards, spectres laying snares for those preachers may surprise them. Incessantly and constantly, O Lord, will I protect such a preacher. And when a preacher who applies himself to this Dharmaparyâya shall take a walk, then, O Lord, will I mount a white elephant with six tusks, and with a train of Bodhisattvas betake myself to the place where that preacher is walking, in order to protect this Dharmaparyâya. And when that preacher, applying himself to this Dharmaparyâya, forgets, be it but a single word or syllable, then will I mount the white elephant with six tusks, show my face to that preacher, and repeat this entire Dharmaparyâya. And when the preacher has seen my proper body and heard from me this entire Dharmaparyâya, he, content, in high spirits, ravished, rejoiced, joyful, and delighted, will the more do his utmost to study this Dharmaparyâya, and immediately after beholding me he will acquire meditation and obtain spells, termed the talisman of preservation, the talisman of hundred thousand kotis, and the talisman of skill in all sounds.
