One could visualise a void, empty of possibility, as the condition prior to the emergence of being, but if it were empty of possibility, how did the possibilities represented by the being/cosmos emerge? Even the capacity to imagine such a void constitutes that void as evocative/representative of a possibility, the possibility of its being imagined.
Could the ability of the human mind to conceive the idea of the Absolute, even the Unmanifest, imply that even if the Absolute were eventually apprehendable by the mind, at whatever levels of adequacy or inadequacy, the Absolute would not constitute/be the ultimate possibility of human conception, since, perhaps, what the mind can conceive, it can also go beyond, at least in conception, and perhaps in apprehension.
But, beyond the notion of the Absolute, is that of the Unmanifest, which becomes manifest only as it is actualised through realization by the mind. So, in relation to this conception of primordial possibility, the boundaries of possibility recede as they transcended. But then! Does that imply that being could be centred on Something, on That which is fundamentally inconceivable?
