With each excursion out of the body I would return with answers. Sometimes these answers would be small and sometimes they would be big. As one becomes proficient in out of body travel, one starts to remember past events and experiences not related to the present life history. Apparently, just as one can remember their physical past while in the physical, one can also remember their nonphysical past while nonphysical. These memories are not forgotten when one reenters the physical after an excursion. Through out of body exploration one can begin a self discovery journey that will lead to the knowledge of who and what we are. Multidimensional beings momentarily inhabiting a physical body.
Just as there are definite geographical locations in physical reality, there are also definite geographical locations in nonphysical reality. As humankind begins to explore the nonphysical realities, they will also begin to map them and to determine how we can use them practically. Humanity may find a way that we can use this knowledge to instantaneously travel physically from one location of reality to another.
Many different branches of study can also use OOB travel constructively. Oceanographers can use it to study deep within the oceans without needing expensive technological equipment or dangerous missions. Since OOBEs are not subjected to time-space constraints, archeologists can use it for expeditions into the past. It can also be used for deep space exploration. The possibilities for OOB travel are infinite and with each exploration we gain a better understanding of, the big picture.
