This is as I heard from the Blessed One. Those days, the Blessed One was traveling in the kingdom of Kosala with a large community of monks. At that time, a large number of youths passed by mocking others, not far from the Blessed One. The Blessed One saw the large number of youths mocking others passing by.
Then, on realizing the conceit of ordinary people, the Blessed One on that occasion exclaimed:
“With confused minds,
they speak whatever comes to their mind,
pretending to be wise.
They go around babbling as much as they like.
These conceited individuals,
don’t know what they are talking about.”
