Martin Heidegger refers to it as a ‘bringing-forth’, using this term in its widest sense. He explained poiesis as the blooming of the blossom, the coming-out of a butterfly from a cocoon, the plummeting of a waterfall when the snow begins to melt. The last two analogies underline Heidegger’s example of a threshold occasion: a moment of ecstasis when something moves away from its standing as one thing to become another.
