What is sleep?
We may as well ask ourselves “what is language?”
Sleep is in general a measure of the absence of language, of incessant mental chatter and an accelerated internal narrative that our minds are quite naturally oriented towards.
If we might assert that language is a technology as much as it is the cognitive hyper-extension of all those interior surfaces of intelligence and human being, we might similarly infer that sleep as peace and restful recuperation is quite dramatically the inverse, the absence of all technologies.
Is it such a surprise that technology – in all its manifestations – quite clearly leads us away from sustainable mental balance or peace?
