THINKING IS AWANDERING AWAY, going astray. Whenever you think about anything, immediately
you have started going away. I am here, you can be with me – but if you start thinking about me you are on a journey going on and on, and the more you get into thinking the further away you will be.
Thinking is a way to escape from reality; it gives you an inner direction, it makes you a path in your
mind and you move on it. A thinker is never here and now, he is never in the present, he is always somewhere else. A meditator is always here and now, he is nowhere else. That’s why thinking is the only barrier in meditation. You have to become aware, and by and by, the more you become aware, the more you stop cooperating with thinking.
