Vibhajjavāda is an umbrella classification for Buddhist denominations that promote analysis as a primary tool for developing 'insight' (Sanskrit: prajñā). This doctrine holds that the first step to insight is to be achieved by the aspirant's experience, critical investigation and reasoning; instead of by blind faith.

Nomenclature and etymology

Vibhajjavāda (Pāli) or Vibhajyavāda (Sanskrit). The word Vibhajjavāda may be parsed into Vibhajja, loosely meaning "analysis" and vāda holding the semantic field: "doctrine", "teachings". Hence, the term "Vibhajjavāda" may be rendered into English as "the doctrine of analysis".

Exegesis

The Third Buddhist Council, under the leadership of Moggaliputta Tissa sthavira emphasized this analytical approach. Some sub-divisions of Sthavira School which adopted this approach were regrouped and termed as the followers of Vibhajjavāda. Those not included in the Vibhajjavāda group were the Mahāsānghikas, Sarvāstivāda and Sammitīya, who were regarded as having the ‘wrong view’ by the Vibhajjavādins, according to the Kathavatthu, a work ascribed to Moggaliputta Tissa.

After the Third Council, the Vibhajjavādins gradually evolved into four groups: the Mahīśāsaka, Kāśyapīya, Dharmaguptaka and the Tāmraparnīya. Theravada is descended from the Tāmraparnīya, which means 'the Sri Lankan lineage'. On the other hand, some sources suggest that Mahīśāsaka, Kāśyapīya and Dharmaguptaka did not evolve directly from the Vibhajjavādins, although an original connection between these groups is posited due to the similarities of their respective Vinayas.

The Vibhajjavadins are claimed to have seen themselves as orthodox Sthaviras.

According to Sinhalese tradition, Buddhism under the name of Vibhajjavāda was brought to Sri Lanka by Mahinda, who is believed to be the son of Emperor Asoka, an event dated by modern scholars to 246 BCE.

The Theravāda descendants of this school claim that Vibhajjavāda represents doctrinal orthodoxy. However, proponents of this approach are frequently mentioned in the Sarvāstivādin Mahā-vibhāsa, where they are viewed as the type of heretics who "make objections, who uphold harmful doctrines and attack those who follow the authentic Dharma". This characterization was a response to the methodology and type of arguments recorded in the Kathavatthu, where part of Sarvāstivādin doctrines is refuted. Only three questions in the Kathavatthu are directed against Sarvāstivāda, which probably means that the rest of the Sarvāstivāda doctrine did not differ much from the Vibhajjavādins at the time of the Third Council.

Vibhajjavādī as a characteristic of Bodhi

The term vibhajja-vādī occurs in MN 99 and AN X.94, though not in the sense of a separate school, but as a characteristic of bodhi and the Shakyamuni Buddha himself: "Now, by blaming what is blamable and praising what is praiseworthy, the Blessed One is a 'discriminating teacher' (vibhajja-vadī) and is not one-sided in his teaching" (AN X.94).
