Where is the wisdom we have lost in knowledge? Knowledge gives us information. Wisdom gives us light on the way. Knowledge is skill. Wisdom is a quality. Knowledge can be learned. Wisdom can only be distilled from those places in life where knowledge is not enough to really explain what was happening to us, or information failed to resolve what was happening to the other.
I think the most essential thing in one's life is silence. What is silence? We think if we are quiet, we are silent. But we must come to silence without desire and wanting, otherwise we are not silent.
