Is there a metaphor in the poem blessing by James wright?

In the poem "Blessing" by James Wright, there is a metaphor in the first line: "I have been lying here in the dark." This is a metaphor for the speaker's experience of the world, as he feels lost and alone, surrounded by darkness. The metaphor is further developed in the second line: "In the vastness of the night." The speaker is emphasising his smallness and insignificance in the face of the universe. He feels insignificant, like a tiny speck of dust in a vast, incomprehensible cosmos. This metaphor of darkness and vastness is used throughout the poem to create a sense of awe and wonder at the mystery and beauty of the natural world.
