yes you can, if you are dedicated to learning it. it depends on the person, it is easier to learn from a seminar than anything else, then a little harder is the study course, then the book. but if a person takes the seminar and they dont really dedicate time to learning(not likely if they spent so much money), then a person like youngprer reads the book, he will learn more than the person who took the seminar. it is completely possible to learn the same or more by reading the book, but you have to try.
