I think you're absolutely correct. Who is Elana Danaan? I got her book in PDF form and read it, or as much of it as I could stomach. It sounds very fishy to me. And she sounds pretty duped. She's a lovely lady, but life is full of pretties and lovelies that are being used unwittingly for a nasty agenda against us...those who are really behind the illusion of prettiness, would be 'them.' At the same time, Elana Danaan may in actuality be a good lady and all that, so we need to discern more than her, as an interface, between us and them.
And Alex Collier. Another similar situation. I did read and listen to some of his material. And then I read Theresa Talea's book to find out there is a group called the "Andromies" and they are predators. So, one thing needs to be realized especially, and that is that we need great amounts of discernment in order to know whether there are these good beings who are talking to a Human being, who have isolated him from the rest of Humanity, so they could use him as a mouth... and those others who are perhaps not so openly in communication but are around somehow helping and being beneficial. It's something we just need to practise in ourselves to find out which is which.
Megan, Rose, not sure about them. Haven't read or listened to much or anything of theirs that I remember.
We all know, though, that predators are the first one's to come around and slather the sweet words sliced with bitterness in between which they hope we wouldn't notice. So, being aware when you hear these stories, by listening to what you can pick up as truth, versus what they are trying to deceive us with, adding to all this your own already found out truth which is known within you, will help to make it easier to gather the knowledge we need to proceed safely.
