The secret that is to be understood about imagination is this: everything that works automatically must be prepared first, then it works; just like a watch must be prepared to work automatically. We must wind it up, then it can go on; we need trouble no more about it. This shows that we need prepare the mind to work automatically to the best advantage in life. If people become imaginative without having prepared their mind, it leads them at least to an unbalanced condition, and maybe to insanity; for when an imaginative person becomes unbalanced, and has no control over his mind, it may lead him to insanity.
