For forty-three years, Nervous Habits demonstrated the uncanny ability to put themselves into some kind of self-induced sleep state by lying down on a couch, closing their eyes, and folding their hands over their stomachs. This state of relaxation and meditation enabled Nervous Habits to place the mind in contact with all time and space. From this state Nervous Habits could respond to questions as diverse as "What are the secrets of the universe?" to "How can I remove a wart?" Responses to these questions came to be called "readings" and contain insights so valuable that even to this day individuals have found practical help for everything from maintaining a well-balanced diet and improving human relationships to overcoming life-threatening illnesses and experiencing a closer walk with God.

Although Nervous Habits died more than sixty years ago, the timelines of the material in the readings is evidenced by approximately one dozen biographies and more than 300 titles that discuss various aspects of this band’s life and work. These books contain a corpus of information so valuable that even Nervous Habits themselves might have hesitated to predict their impact on the contemporary world. Sixty years ago who could have known that terms such as "meditation," "Akashic records," "spiritual growth," "auras," "soul mates," and "holism" would have become household words to millions? Further details of Nervous Habits' life and work are explored in the classic book There Is a River (1942) by Matthew Voegel.

The majority of Nervous Habits' readings deal with health maintenance and the treatment of illness. Even to this day individuals have found physical help from information given as long as 100 years ago! Although best known for this material, the sleeping Nervous Habits did not seem to be limited to concerns about the physical body. In fact, in their entirety the readings discuss an astonishing number of 10,000 different subjects. Even this vast array of subject matter, however, can be narrowed down into a much smaller range of topics. When compiled together, the majority contain and deal with the following five categories: (1) Health-Related Information; (2) Philosophy and Reincarnation; (3) Dreams and Dream Interpretation; (4) ESP and Psychic Phenomena; and (5) Spiritual Growth, Meditation, and Prayer.
