To leave everything and just sit under a tree and feel happy is not difficult--anybody will feel that way. Nothing to do, you can be detached; everything to do, you become attached. But when you do everything and yet remain unattached, when you move with the crowd, in the world and yet alone, then something real is happening... And remember, and always keep it in your heart: truth, love, life, meditation, ecstasy, bliss, all that is true and beautiful and good, always exists as a paradox: in the world and not of it. With people, yet alone; doing everything, and being inactive; moving and not moving; living an ordinary life, and yet not being identified with it: working as everybody else is working, yet remaining aloof deep down. Being in the world and not of the world, that is the paradox. And when you attain this paradox, the greatest peak happens to you: the peak experience.
