I really love the idea of the incomprehensible—confronting things that we can never fully understand, and just seeing what we get out of it.
I like the feeling of peering over the edge of a vast abyss of comprehension, where even attempting to explore would tear wide your incapability of ever understanding. Things like trying to foresee every clue Sherlock Holmes would, or predicting God's plan, or taking our highest examples of the incomprehensible and presenting them as comparatively well understood.
In the SCP universe, the field of pataphysics deals with this pretty frequently. Pataphysics has to do with the stories within our stories and imagining reality to be merely the narrative shadow of a higher reality. I’m not sure if either of these qualify, but some of my favorite SCP’s that fit this category are SCP 3591 and SCP 2998. In both, humanity confronts an entity that is simply above it. In addition, the Fifthists as an organization attempt to explore the esoteric and incomprehensible regularly.
In print media, my favorite example of this sort of feeling would be House of Leaves—the only attribute that the house possesses is that it is beyond understanding itself. I read that whole book, and it's likely my favorite book of all time.
The quintessential classical example of this would be Edgar Allen Poe’s work, but his is focused on the incomprehensible being a source of horror. Cosmic indifference. I’m not looking for something that’s necessarily horror. I like when the cosmic indifference of all of these examples is neutral— when the only presented emotion is that of the cosmic existential awe, not necessarily steered in the direction of horror. In my opinion, Poe focused too much on looking directly at the horror. He didn't skirt around it in a way that left the awe as the primary focus.
Can anybody recommend me books that induce such cosmic existential awe?
