"a very definite atmosphere"

The real subject matter, the ultimate raw material that I find in myself without any interference of will, is a certain dynamic state, completely "ineffabilis" and totally incommensurate with poetic means. Even so, it has a very definite atmosphere, indicating a specific kind of content that grows out of it and is layered upon it. The more this intangible nucleus is "ineffabilis" the greater its capacity, the sharper its tropism and the stronger the temptation to inject it into matter in which it could be realized.

~ from a 1939 letter written by Bruno Schulz
