Until the sutras were handed down
After Shaka's death, the disciples are said to have held a council (ketsujū) to gather and confirm the teachings. A Sōtō school explanation says that Makakashō led the assembly, Ānan recited the teachings, Upari recited the precepts, and the other disciples checked them.
