Ilmu Bebas Pakai - Free usable knowledge

Read this story. If I have 1 coin and you have 1 coin, then we exchange our coin, what will happen? Both of us still have only 1 coin. What if I give you mine? You have 2 coins but I don't have any. It is going to be a different story if each of us have 1 book (knowledge)? If we exchange the book, you will have 2 books and so will I. Got the point?
