The difference between blue ray and green ray.

[Verum Occultum]

Where is blue ray described as the density of rest?  I have not seen this description, if you could point it out, I would be much obliged.

I think he means the blue ray density contains more of a contemplative orientation wherein the focus of self and other self is tipped more towards the self. Ra has said something along the lines: "The fifth density is an extremely free density" which I tend to connect with solitude. Compassion or universal love is put into motion in the self and towards other selves, but to discover wisdom is an inner journey. Of course, you may listen to a variety of teachers, but in my understanding the fruits of insight must grow deep within the self. If you solely rely on the understandings of your teachers, the universe will test you in a way that will bring4th your own personal insight; if you find yourself in a shortage of insight you will find a challenging task. Therefore, I think and believe the fifth density offers a lot of space/time for these personal contemplations, for example contemplations of the previous incarnations in where the naïve fourth density entity did not see the many orientations different actions could produce. So the fifth density is a realm of self-reflection mainly: understanding the self as the co-creator of reality. This does not negate the dialogues between teachers from higher and lower densities or those of the inner family within the fifth density experience. Rather, these aspects color the total experience just as you may put ingredients into your food to make it tastier.

EDIT: It's really cool to wonder if similar conversations are discussed among other third density planets. How would their communication flow? What of their ways of being? Did a higher density entity bring them that information? Do they also have a type of 'internet' (not a Social Memory Complex)? Did they also think the same thoughts I just thought? "Oh, hi there!"
