Yes, you can learn with just the book.
Many have learnt with just the book because everything you need to know is in the book. Some people just find it easier to work with the tapes rather than just the book because the book alone doesn't provide the motivation and the tapes help you to enter the accelerative learning state a little easier. It takes practice with the book or with the tapes. The forum provides a lot of tips and advise.
