One man has discovered that by running there is no need to meditate, just by running meditation happens. He must be absolutely body oriented. Nobody has ever thought that by running meditation is possible - but I know, I used to love running myself. It happens. If you go on running, if you run fast, thinking stops, because thinking cannot possibly continue when you are running very fast. For thinking an easy chair is needed, that's why we call thinkers armchair philosophers; they sit and relax in a chair, the body completely relaxed, then the whole energy moves into the mind.
