You know you have to read "between the lines"to get the most out of anything . I want to tell
you something important during your reading .
you shouldn't mark books, wich isn't yours.People who lend you books expect you to keep them clean If you think it useful to mark books , you will have to buy them.
There are two ways in wich one can own a book . The first is to get the right by paying
for it just as you pay for clothes and furniture .But full ownership comes only when you
have made it a part of yourself. And thinking can express itself in words,spoken or written.
