Why does falling back from a state of effortlessness happen, and can it be prevented?

According to Osho, falling back from effortlessness is natural: life moves in waves of peaks and valleys, happiness and misery. The problem is our division—wanting peaks, rejecting valleys. You can’t prevent alternation, but you can prevent suffering: accept both equally (or renounce both). Acceptance transforms ‘misery’ into simple fact; rejection breeds pain. Equal-mindedness lets you transcend the swing, remaining undisturbed as states change.
