A parable extended

But the kingdom of the evil one looks like a treasure that a person finds in a field, and then goes out and sells off his true treasure in order to buy the field. When he has purchased the field, he guards it jealously and lives in continual fear of losing its contents. He visits it only in darkness, when no one might see what he is up to, which prevents him from either seeing the worthlessness of what he has purchased or understanding what he has given up to own it. And it gradually consumes his life and steals all of his joy.
