On one occasion the Blessed One was dwelling at Sāvatthī in Migāramātā’s Mansion in the Eastern Park. Then Visākhā Migāramātā approached the Blessed One, paid homage to him, and sat down to one side. The Blessed One then said to her:
“Visākhā, observed complete in eight factors, the uposatha is of great fruit and benefit, extraordinarily brilliant and pervasive. And how is the uposatha observed complete in eight factors, so that it is of great fruit and benefit, extraordinarily brilliant and pervasive?”
All as in 8:42, including the verses. [256–258]
