To see what is, is really quite arduous. How does one clearly observe? A river when it meets an obstruction is never still; the river breaks down an obstruction by its weight or goes over it or works its way under it or around it; the river is never still; it cannot but act. It revolts, if we can so put it, intelligently. One must revolt intelligently and accept what is intelligently. To perceive what is there must be the spirit of intelligent revolt. Not to mistake a stump needs a certain intelligence; but generally one is so eager to get what one wants, that one dashes against the obstacle; either one breaks oneself against it or one exhausts oneself in the struggle against it. To see the rope as the rope needs no courage, but to mistake the rope for a snake and then to observe needs courage. One must doubt, ever search, see the false as the false. One gets power to see clearly through the intensity of attention; you will see it will come. One has to act; the river is never not-acting, it is ever active. One must be in a state of negation, to act; this very negation brings its own positive action. I think the problem is to see clearly, then that very perception brings its own action. When there is elasticity there is no question of right and wrong.
One must be very clear within oneself. Then I assure you everything will come right; be clear and you will see that things will shape themselves right without your doing anything about it. The right is not what one desires.
There must be complete revolution, not only in great things, but in little everyday things.
