Buddhism isn’t a book-based or idea-based religion, but a religion based on observing our human experience first-hand. So studying books is not the emphasis of the teaching, but practice in order to get direct knowledge of the truth within ourselves. Ajahn Brahm explains using the story of the pyramid in the jungle.
