法華經義記 7.74

7.74

「藥王我於餘國」此下是第三獎勸通經之人，就中有五段：第一明如來遣化人為通經之人集聽法眾；第二方亦遣四部眾聽其說法通經；第三明若於山林曠野無人民處，我亦遣天龍八部聽其所說；第四言此人若在殊方異立，令通經之人時復得見我身；第五言此人若通經之時有忘失章句者，我以神通道力令其不忘。

From 'Bhaiṣajyarāja, I in other lands' downward is the third [section], encouraging and exhorting persons who propagate the sūtra. Within this are five parts: first, explaining that the Tathāgata dispatches conjured persons to assemble an audience to listen to the Dharma for the person who propagates the sūtra; second, that he also dispatches the fourfold assembly to listen to their preaching of the Dharma and propagation of the sūtra; third, explaining that if in mountains, forests, or wilderness places where there are no human inhabitants, I also dispatch the heavenly beings, dragons, and the rest of the eight classes to listen to what they preach; fourth, stating that if this person is situated in another land and a different place, the person who propagates the sūtra is enabled to see my body from time to time; fifth, stating that if this person forgets chapters and verses when propagating the sūtra, I, by the power of supernormal paths, cause them not to forget.
