Here is a pasage from the Tao Te Ching , the classic book of integrity and the way by LAO TZU

Without going out-of-doors,
     one may know all under heaven;
Without peering through windows,
     oner may know the Way of Heaven;

The farther one goes,
The less one knows.

For this reason,
     The sage knows without journeying,
          understands without looking,
          accomplishes without acting.
