Another means of communication used by benevolent beings is through the use of a host human body.  A "walk-in" may be defined as someone who occupies a body they have not occupied since it's birth.  In other words, a person was born into a body, but later vacates that body and allows another personality to literally walk into the body and take over control of the body and life of the original person.   After a specific task has been performed by the other personality, that soul may leave the body and enable the original soul to return to their body.  An important distinction regarding this type of "out of the body" experience is that it is consensual.   In 1977, a highly evolved being appeared before the wife of a dentist in Tacoma, Washington, by the name of J.Z. Knight.  For two years, this being, who could only be seen and heard by Ms. Knight, created miracles and bestowed upon her spiritual enlightenment.  The entity stated that he once lived on Earth as a human being 35,000 years ago.  He was a mighty conqueror known as the great Ram of the Hindu people who ultimately learned to conquer himself and ascend from this plane.           J.Z. Knight agreed to allow this being to enter her body, for various periods of time, so that others could be taught spiritual development.  Today, this entity, known as Ramtha, conducts classes and retreats at the Gnostic School of Enlightenment in Yelm, WA.  Although Ramtha exists with the interstellar entities from Andromeda, he cares greatly about expanding the consciousness of humanity on this planet where he once struggled, as a human being, to exist.   Ruth Montgomery sought counsel from her spiritual Guides about another walk-in, who stated: Charlotte King came into that body as a Walk-in from Sirius about eight years ago, when she found that the occupant of a particularly sensitive body wanted to leave, and that this body would work well for her in her mission to warn earthlings of imminent disasters and give them time to evacuate dangerous areas, if they wanted to survive in their present bodies.  She is not quite the phenomenon that you believe, for there are others throughout the world with similar gifts of sensing earth changes and alterations beneath the earth's crust.  Hers is not a karmic indebtedness, but a divinely given ability to help others, through her alerts."
