We have learned that there are three stages for any creature to be perfected: the formation stage, the growth stage and the completion stage. The number 3 is important. The number 3 appears throughout the natural world which consists of minerals, plants and animals. For example: a face consists of three parts: the eyes, the nose and the mouth. Grasping a hand indicates number 3. Like this: One, two, three. Grasping the hand means number 3. The eyes are also connected to three points. That is to say that the focal point connects three points.

In this respect the number 3 is needed. In Oriental thought, though not in Western thought, it is held that the cosmos is Heaven-Earth-Man. Also, the world is top, middle, and bottom. Even a circle should pass three points. A straight line must connect three points. All of these should be interconnected, from this point of view.
