The mind projects the satisfaction of its various desires, this partly for planning and partly for proritisation between different desires. The projection takes the form of imagining this satisfaction, and the stronger the desire the more vividly it does so, pushing the desire forward as an immediate motive. The imagination here also functions as a form of magic, as if it were a power to create the desired result, and so making a bet against reality. When this bet fails the resulting pain is proportionate to the imaginary satisfaction and invokes an imaginary defensive response rather than merely serving as a corrective to planning. It is these imaginary defensive strategies that give rise to the egotistic ego; its reality is built out of them and their complex co-ordination, just as the reality of the 'outer' world is built out of the co-ordination of perceptions. The defensive strategies become ends in themselves giving rise to the appearance of ego-drives.
