Of Nothingness and Becoming

When one attains the highest possible level of enlightenment, one extinguishes all self and effectively becomes nothing in relation to a state of becoming. What happens, then? Does one stagnate within this blissful state free of the cycle of life and death, or does one become the inadvertent victim of becoming? When one has surrendered all will and self, one is no more. That also implies that one is no longer immune to the spontaneous expression or imposition of the self. Is there a backwards link between nothingness, and existence, where nothingness "evolves" to existence, starting again at the most rudimentary of existences that is the closest to nothingness and no-self? If so, then there may well be a stage beyond Nirvana, even though one will invariably be essentially different once one re-emerges as a new existence. The old self was surrendered and is no more, but nothing guarantees that a new and completely different rudimentary self cannot arise from the nothingness of the old self.
