I'd be lying if I tried to convince you that there is a specific spirituality category. All reading is spiritual to me. All books listed have been spiritually impactful in one form or another. For that reason, I've arranged them alphabetically (by title). However, I am also categorizing them into Children, Fiction, Non-Fiction, and Poetry. This list is ever-changing based on books I've forgotten or books I'm reading.
My list of books that inspire me:
