2.522

若聞如是等經。信解受持讀誦以方便力為諸眾生分別解說顯示分明。守護法故。是名法之供養　此二明供養。文二。此初信行讀誦。肇曰。如是等經盡諸佛法身也。若聞斯經能信解護持宣示分明。令大法增廣名法之供養。養成法身也。

"'If one hears such sūtras, believes, understands, upholds, reads, and recites them, and through the power of expedient means analyzes, explains, and clearly reveals them for the sake of all sentient beings, protecting the Dharma, this is called the offering of Dharma.'" / This second clarifies the offering, in two parts. This first is practice based on faith: reading and recitation. / Sengzhao says: "Such sūtras fully embody the dharmakāya of all Buddhas. If one hears this sūtra and is able to believe, understand, protect, uphold, and clearly reveal it, causing the Great Dharma to increase and expand, it is called the offering of Dharma, for it nurtures and accomplishes the dharmakāya."
