Pattalee is a very generous person who seeks the best in each of us. Her style in this text does not reveal what she expects the book to accomplish.
She is more then just a tutor. She has a geninue interest in the growth of each pupil.
If you had a half hour of instruction from Pattalee and then this book, you could easily understand that she is not just passing on what works for her, but the free thinking and ethical standards she uses in her own works.
