Thereafter rose Desire in the beginning, Desire, the primal seed and germ of Spirit. Sages who searched with their heart's thought discovered the existent's kinship in the non-existent.
To posit that nothingness has desire is a very abstract and interesting notion for such an old text. Maybe that desire links to the void wishing for something to exist, to define itself, to be opposite of? Maybe it refers to our desire for creation leaping from the void and giving ourselves the ability to build and make. Very interesting either way.
