According to Osho, the lamp flickers not as a necessary growth phase but because the mind drags in tomorrow—craving permanence and worrying, you create the gusts that shake it. Equanimity is steady; projection makes it tremble. Remedy: drop the future, live this single moment totally. Drinking the now strengthens your capacity for steadiness in the next, forging a chain of presence rather than anxiety.
Your calm wobbles because you worry about the future; stay with this moment and it will steady itself.
