10:24 - The likeness of this world's life is only as water which We send down from the cloud, then the herbage of the earth of which men and cattle eat grows luxuriantly thereby, until when the earth puts on its golden raiment and it becomes garnished, and its people think that they have power over it, Our command comes to it, by night or by day,
so We render it as reaped seed; produce, as though it had not been in existence yesterday; thus do We make clear the communications for a people who reflect. (aka harvest!)
10:25 - And Allah invites to the abode of peace and guides whom He pleases into the right path.

As for channeling, I don't wish to delve in as it's fairly personal and I haven't got much experience, just a sliver. However, I can describe the characteristics. It begins with entering a deep meditative state, much like the hypnagogic state we get into when we are hyper relaxed after a very long hard day's work.
This state is induced by an intuitive mindfulness over one's waking consciousness, you lul yourself to a wide awake sleep, a hypnosis. Have you ever been speaking amongst a group of people in tremendous depth only to lose yourself in your own thoughts, then come to, realise everyone has been talking for hours and nobody has any idea what has been said despite being immersed in an incredibly deep and fluid conversation? This is exactly the same state. In both cases, the ego self disappears and the unified higher self takes the reins.
The state is induced by attempting to "lower oneself" into a bath of pure being, in the same way each breath you take as you are nodding off takes you one step lower at a time into all consciousness.
I haven't had spirits open themselves to me and name themselves in such a straightforward way as the RA channelings do. Their presence however cannot be ignored - you look around and count 6 people in the room yet in one's mind there are clearly more than 6 conscious entities in your space. They guide the ebb and flow of your thoughts in this strange way, it's like interference between two radio channels, one of your own mind and another of unknown origin. If you give up your consciousness to them (it's like bandwidth!) then they take over the transmission and you speak things you could not say yourself.
Don't confuse inner chatter with the voice of spirits, when they are there, it is unmistakeable.
The only way I can explain what the spirits I have experienced are is to say they're living patterns of energy which don't possess a body. In the way that you have your personal ego self in your mind, a spirit is another "I am" floating around with its own point of view! I can't do any better than that with such limited experience though, it's like a gnat trying to explain the ins and outs of british humour to a bunch of other gnats.
