To be awake is to be alive.
Literal
Eye [subject-が] is-awake [thing-that-ということ] [topic-は], is-alive [thing-that-ということ] is.
A neatly symmetrical aphorism using ~ということ twice — first to nominalise 'being awake' and then 'being alive' — and joining them with は and である ('is,' the formal/written copula). The frame X ということは Y ということである is a fixed equational structure meaning 'for X to be the case is for Y to be the case,' used for definitions and philosophical pronouncements.
