It is an act of disclosure, and as such it is for Heidegger, a poetic act. Thus the Heraclitean unity of Logos and being becomes at bottom a unity of poetry and being. Heidegger is quite explicit on this point. In order to elucidate his idea that 'that the essence of language is found in the act of gathering within the togetherness of being', Heidegger takes up the question of the origin of language - a question, he says, which has remained unanswered 'not because men have not been clever enough', but because 'the origin of language is in essence mysterious. And this means that language can only have arisen from the overpowering, the strange and the terrible, through man's departure into being.
Language is the primordial poetry in which a people speak being'.
