俱舍論疏 18.47

18.47

"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."
