relax is easy,you don't need to "try",just relax lightly.feel all your muslce are fall asleep.
the "2" just focus on "now",just make you self focus on what you are doing.you can image you are in a timeline,and set yourself at the time "now".
If you PR several books,you can absoutely choose to restate your purpose for each book.But personally I will become tired of this.You can set a common purpose of them,for example "get the new information to apply to my life","get the interest of the book" and so on.Or you can classify the books into the different subject,then photoread as different subject,set one purpose for one subject.
