The Ashtar Command is a kind of interplanetary and interdimensional agreement of several extra-terrestrial cultures. Their goal is to assist civilizations in the process of Ascension, by offering knowledge. The Ashtar Command is under the administrative direction of Ashtar Sheran, and under the spiritual guidance of Lord Sananda, of whom Jesus Christ was one incarnation.
Some (ET-) Personalities of the Ashtar Command are:

It should be pointed out, however, that according to at least three sources, the Ashtar Command has been infiltrated by "Negatively Oriented" Aliens, or at least that on more than one occasion, negatively oriented aliens have presented themselves as "members of the Ashtar Command."
Note that most of the information on the Ashtar Command is channeled, though corroborated by some contactees. Remote viewers, too, confirm the existence of such an organisation.
