In fact it is in imagining and manifesting différance (a la Derrida) that Creation comes into being, by the action of imagining and manifesting "other" and the myriad of possibilities which that dance provides, a system of signification that is maya, the illusory and in truth groundless thing we call and try to signify as "reality." Even light and dark are not truly separate or different, as duality itself is a fiction produced by something not unlike différance.
In a vision (primal as primal might be memory?) I have in mind, the start of the show in each cycle of the expansion and contraction of the universe is Him pressing His linga into Her, a tiny mass of everything reaching out into the void . . . else vice versa to elicit the grand illusory play of duality and maya that is.
