a slave submits primarily to her own nature

… a slave submits primarily to her own nature. The apparent paradox of introvert/extrovert comes to light – and is resolved – when this basic fact is understood. That she requires a material, external focus for her submission, i.e. the dominant, does not alter the fact that on the spiritual level her submission is essentially introverted. One could say that through the dominant she submits to herself by proxy.

– J. Mikael Togneri, in his essay Spirituality In Slavehood
