Answer:
*Before using my answer, I was provided very little context.
The "you that mumbles in the dark" and the "you that draws your veil across the stars" are references to the human tendency to doubt and question the mysteries of the universe. In this context, the "dark" represents the unknown and the "veil" represents the limitations of human understanding.
Step-by-step explanation:
A veil is a piece of fabric that is used to cover or conceal something. In this case, the "veil" is being used figuratively to describe the way that humans obscure their view of the universe by doubting and questioning its mysteries. By "drawing the veil across the stars," the speaker is suggesting that humans are hiding the true beauty and wonder of the universe by focusing on their doubts and fears.
