Dear Pali friends,

Can someone please help me with a sutta reference?
There is a story in the canon somewhere, I believe,
where the Buddha talks about floating his bowl on a
river and it travelling upstream, and this was an
analogy with those who follow the Dhamma having to
swim against the stream of society. I may have
botched that synopsis, but if someone could point me
to the source, I would be most grateful.

With metta,
John
