MP, I actually liked what you originally wrote and appreciated your candor. 
The techniques lead to an understanding of the concepts. You forget the specific techniques because, as I often say “an armbar is an armbar is an armbar.”
Actually, it’s the other way around. At least in my school.
I don’t view Tai Chi as a menu of techniques that lead the student to a conceptual understanding. I teach a movement principle by not teaching it directly. I skirt the core of the principle with extraneous aspects of the movement so that the player can draw from their internal experience of moving, and formulate an understanding that applies to their current level of relaxation and coordination (energy management) as they work within the parameters of Tai Chi’s structure principles.
As the practitioner begins to learn about energy, they begin to look at the methods of acquiring refined energy management as a 3-dimensional model. I call it “stratification.” It goes like this:
I show a student how to perform the basic figure-8 pattern of movement and recovery with their hands at first, as in Corn-grinding or another Chi Kung exercise we just call figure-8s. Corn-grinding is first introduced as a reciprocating circular pattern done with the hands. As we continue the exercise, I explain the ideas of centerline integrity, rotational and extension theory, and how the waist is used to initiate the pattern theyÕre describing with their arms and hands. This takes about 5 minutes, and they have the idea of movement being the essence of their energy managment and tactical possibilities/options.
The Figure-8 is one of the staples of Tai ChiÕs energy management. It allows smooth, eliptical recovery at all levels of movement from the center of the spine on outward to the full extension of the limbs.
The core of movement isnÕt the paradigm contained in technical execution, nor is it dealing with a concept or a particular movement method. ItÕs all three things being practiced in one. As the idea begins to take form, it supplies a paradigm for developing the concept which will imbue sound movement skills, and specialized techniques much like a Judoka’s tokui-waza.
Corn-grinding is a ten-minute introduction to the 3-dimensional modeling of how to use hooks/circular hand method with relaxed, smooth recovery during a series of reciprocating rotations. As a form of tactical application, corn-grinding transcends the mental/intellectual contrivance-based approach to technique, and allows the practitioner to NOT fight - Just manage their energy as the body is set in motion. The opponentÕs targets are just things that get in the way of the movement.
The same approach applies to “submissions,” fast-wrestling, and everything else combative in their Tai Chi.
Tai Chi might be a concept in the way that Judo is “maximum efficiency, minimum effort,” but it also constitutes a set of techniques used to take advantage of that concept. These would be identifiable to another Tai Chi player, yes?
Yes and no. Another Tai Chi player may not visually identify with what I described, as in an MMA match, unless they trained with the person they were watching. But they would definitely feel it, as in an MMA match or sparring for same.
