Purposive action has little need for memory, or such need as it has, especially in the short-term is served with maximum efficiency and economy, recruiting adjacent systems where convenient. Of itself we could say it has no need for a record of its actions and 'takes out the garbage' on a continuous basis. This is very different from what you might call the self in its deeper sense whose whole mode of awakening is an anamnesis, a resurfacing of forgotten intuitions and immediate knowledge. This means that the immediacy in purposive action, such as in introspection or thought-free meditation, is not a comprehensive or good model of consciousness. In the ongoing adventures of life there is no excuse for incurring the overhead of a detailed sensory and ideational memory, you happily dispense with this, until perhaps 'in tranquility' you choose to recollect the events. And yet, there is tremendous pleasure and even a kind of spiritual significance, in a good literary description of such an adventure - as if protagonist or narrator or some combination of the two, actually commanded the excess of psychic energy needed for detailed recall of vast amounts of ancillary detail. This is pure aesthetic value when done well (which is all too rare) and insofar as it tickles anamnesis is somehow also spiritual, evoking the system behind, meta or contextual to purposive action.
