concreteness

Night doesn__ fall for my eyesBut my idea of the night is that it falls for my eyes.Beyond my thinking and having any thoughtsThe night falls concretelyAnd the shining of stars exists like it had weight.

But it is also a power which has, like everything human, its negative side, in the desolating sense of rootlessness, vacuity, and the lack of concrete feeling that assails modern man in his moments of real anxiety.
