No apologia, no exegeses will explain sinkdog. The apophatic definition of sinkdog is a being of thirst and of grime. Do you see? The insight such theologies as those of the sages provide offer us no salve, bring us no closer to enlightenment.
Sinkdog appears to be a contradiction, existing on both sides of several dichotomies. But this neither hinders Sinkdog's existence nor our ability to appreciate that existence. If there is any understanding of Sinkdog, it can be found exclusively through proximity.
