We are allowing information to come through our hand from the other side or from our own higher self. Although there may be no way to prove whether or not automatic writing is real, you will come to your own conclusions. At first it may be hard to understand how easy this process is, but being able to set your analytical side aside will help you to accept the wonderful tool that this can be in your life."

In spiritualism, writing produced involuntarily when the subject’s attention is ostensibly directed elsewhere. The phenomenon may occur when the subject is in an alert waking state or in a hypnotic trance, usually during a séance. What is produced may be unrelated words, fragments of poetry, epithets, puns, obscenities, or well-organized fantasies. During the late 19th century, at the height of popular interest in the phenomenon, inspiration for automatic writing was generally attributed to external or supernatural forces. Since the advent, around 1900, of theories of personality that postulate unconscious as well as conscious motivation, the inspiration for automatic writing has been assumed to be completely internal.
