It seems we need some poetry as much as we need a some wine or beer on occasions. And in our speeches, whenever we speak eloquently, we tend to use poetic language, usually rhymed in some way. Poetry is often found in tomb stones of our ancestors, monuments to the war heroes and martyrs of all justified causes. So people in Heaven are enjoying poetry, too. Many excellent proverbs, maxims, are very poetic, too.
Examples are plenty.
To err humane, to forgive divine. Where honour ceases, knowledge decreases. You see we can find poetry wherever we go. Some knowledge on poetry will help you a long way to project your image as a much more educated and eloquent speaker than without. The reason is simple.
