I also had started with audiobooks but then as i wanted to feel more solemn and to connect to myself more closely and naturally, i switched to physical books. Having a mediator between you and your thing (in this case book) really still makes things a lil uneasy for me. When u can just go with your own comfort listening yourself speak the words in a book in your mind, really makes me feel lot better compared to having a mediator between. It feels like when I’m reading on my own, i am in my natural habitat.
