It's all happening in the brain, in a system fully and unceasingly engaged with itself and with its exterior environment. The system is full of models, maps and updating processes. There are two main categories of these: the sensory field and the action context, which could be called Representation and Will, each consisting of diverse parts connected by peculiar kinds of linkages, glueings, functors. It is not that different maps and models overlap each other and hence are woven together into a single fabric, each realm is built differently, evolved differently, is based on different invariants, different parameters; different parts of the mind speak different dialects, what connects them is paradoxical, is both and neither at the same time. The linkage is itself a different kind of map or model and the seams joining it to what it links, and to other linkings are not natural, they do not arise as the extension of any one part but are artificial, ingeniously and endogenously created. See this as taking place in the integration of the diverse sense worlds to form the sensory field, and in the integration of the action contexts: research, planning, execution, feedback, and most of all in the integration of sensory with action, so that actually neither one is entirely itself without major input from the other. You don't perceive without acting, you don't act without perceiving. It is these complex domain translators and integrators that require, and so define, your self as one of the invariants - the highest-order invariant, the limit invariant - so that all the parts can function together, not in perfect harmony, but brilliantly, symphonically. At some point in the development of all this the lights come on; it's brilliant and so it is 'seen'. It attracts the attention of pure inwardness. And so what is first illuminated is the system of the self, the most brilliant creative leap, the 'I', and so inwardness is identified with the self. That is the starting point. It's an error, but it's a great place to start. Worth spending an aeon celebrating.
