Mahasi Sayadaw served as the pucchaka, the chief questioner, at the Sixth Buddhist Council held in Rangoon from 1954 to 1956, a documented scholarly and ceremonial role distinct from the mass lay meditation method his first article credits him for spreading. The council, convened by the government of newly independent Burma to mark twenty five centuries since the Buddha's parinibbana, gathered monks from across the Theravada world to recite and verify the Pali canon, a documented international undertaking distinct from the single Yangon meditation centre where his first article's story begins in 1949.
In the questioner's role, Mahasi Sayadaw put formal questions to Bhadanta Vicittasarabhivamsa, the council's respondent, working through the Tipitaka section by section to confirm its wording against the participating countries' own editions, a documented textual verification distinct from the abdomen rising and falling technique his first article describes him teaching to lay meditators by the hundreds of thousands. The council's work produced the Chattha Sangayana edition of the Pali canon, still used as a reference text well beyond Burma.
That the same teacher whose simplified noting method carried insight meditation to lay audiences across Asia and eventually to Massachusetts also stood, in the same decade, as the chief questioner verifying the Buddhist canon's own wording at an international council convened for that purpose, marks Mahasi Sayadaw's Sixth Council role as a documented case where the same man served as both meditation's great popularizer and one of the guardians of the textual tradition his method drew from.
