Sure, I'll answer this in an atypical way:
Euclid's Elements or Euler's Elements of Algebra might interest you but they are really old. If you aren't interested in mathematics professionally though I don't see what harm they could do you (on the contrary). A modern introduction to topics of mathematics which also has historical content though would probably be Jan Gullberg's Mathematics from the Birth of Numbers; this is an extraordinary book which is incredibly engaging for the amateur mathematician of any level and a very good introduction to many useful concepts. I don't know of any books which look at mathematics mystically however, I'm afraid, but Guénon apparently had a book talking about calculus which I haven't read and Berkely too, but as far as I'm aware, calculus wasn't really the point of Berkley's The Analyst. I would assume however that these works are largely metaphysical works rather than spiritual, but I couldn't say.
If you want modern reccs then you should check out /sci/. From what I've read, Basic Mathematics by Serge Lang is well liked there and often recommended but I've never read it. Meme answers usually include the Manga Guide to (e.g. Calculus, Analysis, Topology, &c.) but these usually are just okay from what I've skimmed and heard other people say.
For Euclid's Elements, check out these websites

The first is just a website version of vanilla Euclid (mostly from Sir Thomas Little Heath's translations, which are now standard) and the second is based on Oliver Byrne's edition of Elements, which uses graphic representations instead of words to convey meaning within proofs, along with a colorful, almost Modernist, representations and demonstrations though it came out in 1847. Picrel is just a sample from the book.
Still, though, I recommend memorizing vanilla Euclid even if you mainly think in terms of Byrne Euclid.
