The asleep person at the most can dream that he is awake. But that too is a dream. That dream is knowledge. The person who is asleep and thinks that he knows... that is knowledge. But the person who really awakes is wise. Knowledge is a false, plastic substitute for wisdom.
Wisdom is true knowledge -- rather knowing than knowledge, because it has no full point to it. It goes on growing, it goes on flowing. The man of wisdom goes on learning; there never comes a stop.
Don't be knowledgeable, be wise.
