All of the thought´s activities, whether they are positive or negative, are usually experiences that actually strengthen the ego, because they suck life out of the present, out of the Now and timeless, and into time´s self-producing movement from past towards future.
Is it therefore possible for the mind to let life flow back to the present, to allow a total existential presence in the Now?
As the Stoics and the Taoists say, then it can only happen when there is completely silence.
