Imagination
Many people receive an education. They read many books and learn a lot, but it is all bookish knowledge. It is not practical experience. Suppose you have read or heard something about Benares. By reading, you may find out what the polulation is and what temples are there. However, you can't visualize Benares just by hearing about it. If you go there, then what you have read comes alive before you, and there is no longer any possibility of imagination.
