This is a difficult question, as most books do elevate your frequency, at least a little bit. What I've found is that, if your creativity is activated in pursuit of knowledge or profundity in literature, your radar will guide you to the necessary books to read based on your individual goals and curiosities. Every type of book provides something to the reader, but for the sake of my experience, I will talk about the differences between poetry, fiction, and philosophy. Poetry is the beauty of language, philosophy is the morality of language, and fiction is the narrative of language. Reading poetry streamlines carefully curated wisdom to the unconscious. Wisdom is applied poetry-- think the Psalms or Proverbs. There is literature out there that influences you to MAKE beautiful decisions. Creating a decision is different than having a decision created for you. -M
