You can be very much aware that when you are stressed, it always is a sign you have lost the present moment. So, you can choose to re-enter the present moment.
Eckhart TolleThe whole essence of Zen consists in walking along the razor's edge of Now - to be so utterly, so completely present that no problem, no suffering, nothing that is not who you are in your essence, can survive in you. In the Now, in the absence of time, all your problems dissolve. Suffering needs time; it cannot survive in the Now.
Eckhart TollePresent-moment awareness creates a gap not only in the stream of mind but also in the past-future continuum. Nothing truly new and creative can come into this world except through that gap, that clear space of infinite possibility.
Eckhart TolleYou may remember the paradox of time we mentioned earlier: Whatever you do takes time, and yet it is always now. So while your inner purpose is to negate time, your outer purpose necessarily involves future and so could not exist without time. But it is always secondary. Whenever you become anxious or stressed, outer purpose has taken over, and you lost sight of your inner purpose. You have forgotten that your state of consciousness is primary, all else secondary.
