I think this is interesting, as the author describes how their thought process wasn't moving any faster and how it hung balanced on the symmetry. I found it intriguing as it helped me understand the weight the semagrams carry in the character's mind.
I also went through a little bit of an out of body experience when reading through this paragraph. I think it is the way the author weaved the words together that gave me such a feeling.
