find this concept somewhat similar to indian philosophy………………….

We should make ourselves stop trying to explain our own difficulties. Our first impulse is to try to account for them, figure out why what has happened did happen. Sometimes such an effort is beneficial: more often it is distinctly harmful. It leads to introspection, self-pity, and vain regret; and almost invariably it creates within us a dangerous mood of confusion and despair. Many of life’s hard situations cannot be explained. They can only be endured, mastered, and gradually forgotten. Once we learn this truth, once we resolve to use all our energies managing life rather than trying to explain life, we take the first and most obvious step toward significant accomplishment.

……………………. Gilkey revisits the subject through the lens of aging:

Only as we yield to the inexorable, only as we accept the situations which we find ourselves powerless to change, can we free ourselves from fatal inward tensions, and acquire that inward quietness amid which we can seek — and usually find — ways by which our limitations can be made at least partially endurable.

Why is [this] so difficult for most people? because most of us were told in childhood that the way to conquer a difficulty is to fight it and demolish it. That theory is, of course, the one that should be taught to young people. Many of the difficulties we encounter in youth are not permanent; and the combination of a heroic courage, a resolute will, and a tireless persistence will often — probably usually — break them down. But in later years the essential elements in the situation change. We find in our little world prison-walls which no amount of battering will demolish. Within those walls we must spend our day — spend them happily, or resentfully. Under these new circumstances we must deliberately reverse our youthful technique. We must gain victory, not by assaulting the walls, but by accepting them. Only when this surrender is made can we assure ourselves of inward quietness, and locate the net step on the road to ultimate victory.
