Unlike the angel basher, I definitely can say that a lot of the psychic phenomenon is real. Energy never dies; it just changes form as noted by quantum physics. So that means all spirits go somewhere, and why wouldn't they end up here in spirit form in between bodies, or if they have such a traumatic ending, they can't let go until someone helps them? Or angels... we called them here to help us make choices towards the light. We also called the demons here to balance that out. You do have a guardian demon too, if you check. :)
But anyway, if you listen for that still inner voice (and that wouldn't be the one that says kill the president, btw), it will confirm many things for you, like when something is right spiritually. Also, when something spiritually right is heard, a lot of times people get goose bumps or a cold chill. For me it is just a knowingness that has nothing to do with faith. It just feels right, like no religious patter ever did. Sure there were some truths in the patter, just enough to hook the gullible, (because we all are online thru our unconscious mind with the racial unconscious which is the source of our 'truths'). If you learn to go into the racial unconscious in a conscious and aware manner (which I did thru a shaman journey where I actually made it to the higher plane and was able to establish a permanent connection to it), there is a lot of information about earth, humans, non-humans, the history of the world, etc.
Anyway, what I have found as I scanned the racial unconscious about indigos is that they are old spirits, yes, because they have lived many life times on their own planet, which is dying. Their spirits are being brought here because it is so easy to get sucked into a human body, so they can continue their existence. Unfortunately, they can't remember what they are doing here. They just feel out of place, which they are. They were more a predator species than humans are, and so feel a huge need for independence and space (people close means competion for food). They don't understand the rest of humanity's overwhelming need for connection and closeness, and it is one of their biggest challenges and our species salvation. For the first time in the history of the world, the balance is shifting from over-enmeshment towards independence into the middle.
THAT is a prime condition for enlightenment. Over-enmeshment and under-connection are both hindrances, but with the indigos balancing out the primarily co-dependant population of especially the far east, the racial unconscious is actually more centered and the human race is able to get primed for successfully learning to tolerate that light/spirit body that is going to be available to us. It takes the ability to be both a self and stay connected to others to stay comfortably in that state but most people are good at one or the other. With the indigos here, there is a lot more information about how to be a self than was in there before, to balance out all the old information about how to be connected.
The indigos though, aren't a shoe-in for enlightenment. They are not that advanced. Their lessons are just different, as they have to learn to tolerate connection. But indeed they are a very different kind of human. Quite capable of evil if mistreated or toxified as children, just as all the rest of us here can be. They just don't get guilt tripped or manipulated by stuff that the rest of us humans are suckers for because of our enmeshment issues. At least that is the information I have found out there. :)
