green ray can be blocked, blue ray can't?

And here Ra said that the blue ray is the first ray where the radiation is without the necessity of response:

To answer your second question more fully we may say that it is correct that radiation without the necessity of response begins with blue ray although the green ray, being the great transitional ray, must be given all careful consideration, for until transfers of energy of all types has been experienced and mastered to a great extent, there will be blockages in the blue and indigo radiations.

Maybe green ray wants something in response and in this way kind of dependant of others, while blue ray activated entity is completely free?

Hmm. As I've said, I've been working a lot with catalyst where I focus on blue, both communicating myself and consciously using that catalyst to see my own reflection, rather than separating. Two years ago, there would always be a bit of a bad taste in my mouth when conflict with a certain person would happen..when my point of view wasn't recognized (needing a response I suppose). Now I find that when I use the technique of consciously attempting to see the unity with all catalyst, as long as I communicate myself, I'm happy, with no need of my viewpoint being recognized. I'm fine with the other's being because I'm able to see my reflection regardless. That's breaking free from the bonds of others.

So I think your latter point is right. Green ray seems to be the general attitude of keeping the heart open in any given situation. If hate or the unwillingness to have compassion is present, the heart must be closed. "The awareness of all as Creator is that which opens the green energy center."
