金光明最勝王經疏 3.512

3.512

贊曰：此之五逆，三乘通說，總大乘不共逆中當第四逆。誹謗正法亦是破僧。謗佛八正為非正道、說五法為正道，故云誹謗正法。言五法者，大乘未見其文，準一切有部《大毘婆沙》一百一十六，「云何五法？一盡壽著糞掃衣、二盡壽乞食、三盡壽唯一座食、四盡壽常居逈處、五盡壽不食一切魚肉味鹽蘇乳等。」《正理律》攝說五有別，具如彼明。或誹謗正法是大乘第二逆，在此破僧前明者，以謗佛正法同，故在此而說，非屬破僧。

Commentary: These five deadly sins are commonly spoken of across the three vehicles. Taken together, among the unshared deadly sins of the Mahāyāna, this corresponds to the fourth deadly sin. Slandering the True Dharma also constitutes disrupting the Saṅgha: slandering the Buddha's Noble Eightfold Path as not being the correct path and proclaiming the "five practices" as the correct path; hence it is called slandering the True Dharma. As for the "five practices," this text is not found in the Mahāyāna; according to fascicle 116 of the Sarvāstivāda Mahāvibhāṣā: "What are the five practices? 1. Wearing rag-robes for one's whole life; 2. Begging for food for one's whole life; 3. Eating in a single sitting for one's whole life; 4. Always residing in an open, remote place for one's whole life; 5. Not eating any fish, meat, salt, ghee, milk, and so forth for one's whole life." The Nyāyānusāra and Vinaya-saṃgraha explain the five differently, as detailed there. Alternatively, slandering the True Dharma is the second deadly sin of the Mahāyāna; that it is explained here before disrupting the Saṅgha is because slandering the Buddha's True Dharma is similar [in gravity], so it is stated here, not that it belongs to disrupting the Saṅgha.
