7. At that time the Venerable Upavana was standing before the Blessed One, fanning him. And the Blessed One rebuked him, saying: "Move aside, bhikkhu, do not stand in front of me."
8. And to the Venerable Ananda came the thought: "This Venerable Upavana has been in attendance on the Blessed One for a long time, closely associating with him and serving him. Yet now, right at the end, the Blessed One rebukes him. What now could be the reason, what the cause for the Blessed One to rebuke the Venerable Upavana, saying: 'Move aside, bhikkhu, do not stand in front of me'?"
