Wouldn't that be a book filled with blank pages?
Well, two things, really. If it was a similar book on GHANDI, I would assume it referred to his basic, commonly expressed ideas and distilled into one volume - because his wisdom could not be contained in one book. His "essential wisdom" as it were.
The second - well, it's similar. If you contained every wise comment of hers - even ones that weren't original - would it fill a single page? I think I am modestly wise, and I don't think
I could fill one page.
