Jiddu Krishnamurti Commentaries on Living

Curiosity is not the way of understanding. Understanding comes with self-knowledge. He who suffers is not curious; and mere curiosity, with its speculative overtones, is a hindrance to self-knowledge. Speculation, like curiosity, is an indication of restlessness; and a restless mind, however gifted, destroys understanding and happiness.
