Indeed, and were there not For each its procreant atoms, could things have Each its unalterable mother old? But, since produced from fixed seeds are all, Each birth goes forth upon the shores of light From its own stuff, from its own primal bodies. And all from all cannot become, because In each resides a secret power its own.
