I told them that this was the center of gravity of the whole system and of all work on oneself; that now work on oneself was not only empty words but a real fact full of significance thanks to which psychology becomes an exact and at the same time a practical science.
I said that European and Western psychology in general had overlooked a fact of tremendous importance, namely, that we do not remember ourselves; that we live and act and reason in deep sleep, not metaphorically but in absolute reality. And also that, at the same time, we can remember ourselves if we make sufficient efforts, that we can awaken.
I was struck by the difference between the understanding of the people who belonged to our groups and that of people outside them. The people who belonged to our groups understood, though not all at once, that we had come into contact with a "miracle," and that it was something "new," something that had never existed anywhere before.
The external martial arts, although engaging the body as a whole in generating power sequentially, do not use the body in a complete unit as do the internal martial arts. The external styles primarily use "sectional power" (ju bu li), which is a primary reason they are classified apart from the internal arts. A variation of this sectional power in the external arts is the special development of one part of the body as a weapon (iron palm, iron broom, etc.). The internal tends to forego these methods in favor of even development of the whole body, which m turn is used as a coherent unit.
Xing Yi Quan, Tai Ji Quan and Ba Gua Zhang all have unified body motion as their root; hence, they are internal styles. However, since each of these styles emphasizes different expressions of this unified power, they are not the same style.
