The intelligent person is one who lives according to his own light. Whatsoever the risk, he is capable of taking it because he relies on his own intelligence. He knows that the greater the challenge, the greater will be his intelligence; hence he accepts challenges. He lives in danger because intelligence grows only in danger, in insecurity.
The Mediocre man lives according to others. What I mean by a mediocre person is one who has allowed his intelligence to die, who has allowed his intelligence to gather rust. When there is no danger, no insecurity, intelligence dies.
Meditation is the way to sharpen your intelligence more and more. And the more intelligence you have, the closer you are to existence.
