poet Adam Zagajewski said:

Don’t we use the word poetry in two ways? One: as a part of literature. Two: as a tiny part of the world, both human and pre-human, the part of beauty. So poetry as literature, as language, discovers within the world a layer that has existed unobserved in reality, and by doing so changes something in our life, expands somewhat the space of what we are. 

Here's one of his books of poems:
