David Miller of the Group of Forty Project, has been channeling messages from an Arcturian being, Juiano, for 18 years. The Group of Forty Project should really be called the Group of Forty Meditation Project.
There are three videos contained in the link that describe the work of this group and also the tremendous help that we and our Earth are receiving from higher spiritual beings from around the universe. These videos help to describe the dimensional shift that our Earth is making.
