All cravings are the mind seeking salvation or fulfillment in external things and in the future as a substitute for the joy of Being.
Eckhart TolleThe whole movement of happiness, unhappiness, happiness, unhappiness, could be called unhappiness. You're suffering because your state of mind is in flux, moving back and forth. The ego's happiness is really a form of suffering, because it cannot live without unhappiness.
Eckhart TolleWith the egoic consciousness having become so dysfunctional, and now having at our disposal all these enormous technologies and scientific advances, if nothing changes the ego will use those things - as it already has been doing - and will amplify the technology that we now have. The scientific advances, to a large extent, will be used in the service of the ego, and they will become more and more destructive.
Eckhart TolleWouldn't it be wonderful if you could spare them from all suffering? No, it wouldn't. They would not evolve as human beings and would remain shallow, identified with the external form of things. Suffering drives you deeper. The paradox is that suffering is caused by identification with form and erodes identification with form. A lot of it is caused by the ego, although eventually suffering destroys the ego-but not until you suffer consciously.
Eckhart Tolle
