I am not against knowledge; when you are doing something in the world use your knowledge. There, to use wisdom is foolish; there, sitting in a car and meditating is dangerous. There, you should use all your efficiency, all your knowledge, all your know-how; but you should not be confined to it. You should not become obsessed with it, you should be able to go inside. When the work is over you should be able to close the doors to the outside world and return to the inner. Then dance, sing, meditate, love, live. One should be flexible, liquid.
