Following (or leading up to) the schisms, each Saṅgha started to accumulate an Abhidharma, a detailed scholastic reworking of doctrinal material appearing in the Suttas, according to schematic classifications. These Abhidharma texts do not contain systematic philosophical treatises, but summaries or numerical lists. Scholars generally date these texts to around the 3rd century BCE, 100 to 200 years after the death of the Buddha. Therefore the seven Abhidharma works are generally claimed not to represent the words of the Buddha himself, but those of disciples and great scholars.[note 38] Every school had its own version of the Abhidharma, with different theories and different texts. The different Abhidharmas of the various schools did not agree with each other. Scholars disagree on whether the Mahasanghika school had an Abhidhamma Pitaka or not.[note 38]
