Yellow ray in a STO individual

[βαθμιαίος]

Still yellow ray on sphere and in entity both are unused as green ray becomes sufficiently unimpeded.

Not necessarily. We still have to deal in and with society. Consider Schweitzer ("This entity’s yellow ray was bright and crystallized by the efforts needed to procure the funds to promulgate its efforts. However, the green and blue rays were of a toweringly brilliant nature as well.") and Carla ("In a particular entity, let us use this instrument, the rays may be viewed as extremely even, red, orange, yellow. The green ray is extremely bright. This is, shall we say, balanced by a dimmer indigo. Between these two the point of balance resides, the blue ray of the communicator sparkling in strength above the ordinary.").

What?

Yellow ray may BEGIN potentiation only once the green ray has been activated.

Does that then mean that societal navigation/interaction only begins in earnest once the heart is balanced enough to have a singular grasp of what it wants?

It's blue ray that may begin potentiation once green ray is activated.
