Empty your mind. Be formless. Shapeless. Like water. Now you put water into a cup, it becomes the cup. You put water into a bottle it becomes the bottle. You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water my friend. Like that. You see? Ah ha. … What I’m saying, actually you see, I mean it’s a com-bi-nay-shun of both. I mean, here it is the natural instinct and here is control. You are to combine the two in harmony, not if you have one to the extreme you would be very unscientific. If you have another to the extreme, you become all of a sudden a mechanical maaan. No longer a human being. So you, it is a successful com-bi-nay-shun of both … Although hand wise it is very slow and you push it out but all the time you are keeping the continuity going. Bending. Stretching. Everything. You know, suppose, you know, I mean you just keep it moving. Yea it is. I mean to to them, you see, the idea is running water never grows stale, so you just got to keep on flowing.
