俱舍論疏 18.47

18.47

「論曰至障世生天解脫道故」，明破僧罪大。「了法非法」者，天授知佛是一切智、八正是真，自非一切智、五法妄也。「顛倒顯示」者，誑其愚者，顯真是妄、示妄是真等，此無間中為最大罪，一由傷毀佛法身故、二由障世生天解脫道故。出大罪所以。《正理》云「謂僧已破乃至未合，力能遮遏諸異生等，未入正定令不得入，若已入正定令不得餘果，若已得餘果令不得離染，若已得離染令不證漏盡，習定、溫誦、思等業息。」

"The Śāstra says... because of obstructing the worldly paths to birth in heaven and liberation", explaining that schism in the Sangha is the greatest offense. "Understanding what is Dharma and not Dharma": Devadatta knew that the Buddha possessed all-knowledge and that the eightfold correct path was real, and that he himself lacked all-knowledge and the five dharmas were false. "Displaying them invertedly": deceiving the foolish, showing the true to be false and demonstrating the false to be true, and so forth; this is the greatest offense among the anantaryas, firstly because of injuring and ruining the Buddha's Dharmakāya, and secondly because of obstructing the worldly paths to birth in heaven and liberation. This presents the reason why it is a great offense. The Nyāyānusāra says: "That is, once the Sangha has been divided, until it is reconciled, it has the power to obstruct all ordinary persons and so forth: causing those who have not entered the certainty [of correctness] to be unable to enter, causing those who have already entered the certainty [of correctness] to be unable to attain other fruits, causing those who have already attained other fruits to be unable to attain detachment from desire, causing those who have attained detachment from desire to be unable to realize the destruction of the outflows, and causing the practices of meditation, recitation, reflection, and so forth to cease."
