The difference between blue ray and green ray.

[anagogy]

Perhaps it might be useful to try and unpack what 'freely given communication' could possibly be.

It would seem that what "frees up" communication so to speak is the complete acceptance of self and complete acceptance of other self.  

"Ra: The first giving beyond green ray is the giving of acceptance or freedom, thus allowing the recipient of blue-ray energy transfer the opportunity for a feeling of being accepted, thus freeing that other-self to express itself to the giver of this ray."

In the light of this quote, it makes it apparent blue ray is not just objectivity, honesty, or clarity, but rather, pure acceptance of what is observed without judgment as well.  But then, how would an STS being utilize blue ray?  It would seem acceptance of other selves would be as much a miasma to the negative polarity as empathy with other selves is.  Perhaps this is another ray that is not poured outwards towards others, similar to green ray, and simply reserved and directed towards the self in the case of service to self polarization.

But then, I suppose Ra did say that blue ray and green ray were both missing from the STS vibratory schedules.

"Ra: The vibratory rates are not to be understood as the same in positive and negative orientations. They are to be understood as having the power to accept and work with intelligent infinity to a certain degree or intensity. Due to the fact that the primary color, shall we say, or energy blue is missing from the negatively oriented system of power, the green/blue vibratory energies are not seen in the vibratory schedules or patterns of negative fourth and fifth rates of vibration.

The positive, upon the other hand, shall we say, has the full spectrum of true-color time/space vibratory patterns and thus contains a variant vibratory pattern or schedule. Each is capable of doing fourth-density work. This is the criterion for harvest."

Green ray is other, blue ray is self. Consider that blue ray is described as the density of rest, and green ray is a density where overexertion takes place.

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.
