There is now practically a cliche saying in Zen. When hungry eat, when tired sleep. But in that exact same sense there should be, when something needs to be acted on, do it.

It isn't about total passivity, but trying to not to excessive force a position. If you fall in a river, to be passive is to float with it. But the smart move is to swim to the side. Don't try to swim against the flow but with it.
