2.522

"'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."
