Thinking about metaphors is how you think about the hierarchical processing that is your mind, and so the metaphors are themselves hierarchical, and the conformity between them and the emergent world is almost perfect. You can't do more than tinker with this structure, it works too well, and there is no need to do so. What it provides is a way past the dominance of any particular metaphor, such as vision. Rather you can find the seamless inherence of the all experience within the experiencing by attending to the action of the metaphoric. It's not the seeing of a world that arises but the entangled blossoming forth of metaphors in which 'you' are smeared through all the way, without insides or outsides, without a doer and a doing. It's only a first step so treat it with infinite gentleness.
