This book introduces the concept of spiritual travel. Spiritual travel is a form of out-of-body experience done voluntarily to achieve a spiritual goal. In order to have an out-of-body experience, the soul or consciousness of the individual must temporarily leave the physical body. During out-of-body experience, the physical senses shut down. When this occurs, an entirely new world opens up to the individual. Spiritual travel is a special type of out-of-body experience where the individual's awareness is heightened, and he or she is able to make decisions and direct the experience.

The spectrum of experience afforded by spiritual travel is very broad and can include a wide variety of psychic and spiritual states. In most cases, the spiritual traveler is able to clearly remember the experiences and learn from them.

Spiritual travel is sometimes called transcendent or ecstatic experience because it deals with the "inner" senses rather than the physical senses. It also deals with states of being seemingly independent of the physical world.
