Everything flows and nothing abides.

“You have to flow with the river. There is no other way. You can swim against it, and pretend not to be flowing with it. But you still flow with the river.” – Alan Watts

“Only a dead fish flows with the river”

A dead fish is ‘flowed’ by the river.
Flowing with the river is a choice!
‘Give me the power to change what needs to be changed, the power to accept what needs to be accepted and the wisdom to choose between them‘.
