To the extent that definitions ever helped anyone to take a leak in the morning, one of the definitions I have come to like is the definition of "suffering" as "the resistance to pain."
True, the definition above is irritating since there are so many juicy bits to "suffering," so many tears that are wet, so much caring for self and other ... and the word "resistance" suggests an act of will and control where a lack of control is so clearly a key element in complaints about "suffering."
Social righteousness may raise its head and suggest that if there is no resistance, everyone turns into an uncaring blob of existence ... everything serene and taciturn and uncaring. But that would just be more suffering, more resistance.
I wonder what is left when it is impossible to resist and impossible not to resist.
"Going with the flow" is certainly a money-maker, but tends to leave its participants flopping desperately, like a fish on the dock.
