There seem to be some misalignment in our understanding on nothingness, my dear ah sou...
This notion of anatman isn't nothingness or void in the general sense. It does not negate the presence of this physical and/or psychological self.
It is the fundamental understanding that "I" exists, as well as other physical and/or metaphysical manifestation even at the quantum level, and at the same time understanding this "past/present/future I" is fundamentally dynamic and impermanent.
Understanding this impermanence nature in every manifestation of any physical construct, it leads to the termination of suffering. This is the level of my understanding on the notion of "nothingness".
