[37] Then the Venerable Ānanda approached the Blessed One; having approached, he paid homage to the Blessed One and sat down to one side. Sitting to one side, the Venerable Ānanda said this to the Blessed One: "Venerable sir, it is said 'schism in the Saṅgha (saṅghabheda), schism in the Saṅgha.' In what way, venerable sir, is the Saṅgha divided?"
"Here, Ānanda, bhikkhus explain what is not Dhamma as 'Dhamma'; they explain what is Dhamma as 'not Dhamma'; they explain what is not the Discipline (vinaya) as 'the Discipline'; they explain what is the Discipline as 'not the Discipline'; they explain what was not spoken and not uttered by the Tathāgata as 'spoken and uttered by the Tathāgata'; they explain what was spoken and uttered by the Tathāgata as 'not spoken and not uttered by the Tathāgata'; they explain what was not practiced by the Tathāgata as 'practiced by the Tathāgata'; they explain what was practiced by the Tathāgata as 'not practiced by the Tathāgata'; they explain what was not laid down by the Tathāgata as 'laid down by the Tathāgata'; they explain what was laid down by the Tathāgata as 'not laid down by the Tathāgata.' On these ten grounds they draw apart and split away; they perform separate legal acts and recite a separate Pātimokkha. To this extent, Ānanda, the Saṅgha is divided."
