I stumbled upon "poiesis" the same way (researching Heidegger's referenced work). As Heidegger posits: "the essence of technology is by no means anything technological". His notion of poiesis as "bringing-forth" that which was not previously present "into existance" or concealment into unconcealment. This image of poiesis as a kind of revealing leads him to yet another Greek word: aletheia, which literally means "unveiling" or "revealing." It is also the Greek word for "truth".
