I don't think familial bonds count in unconditional love.

Found this little tidbit, seems pretty directly related to the discussion:

84.9 Questioner: Thank you. Going back to the previous session, it was stated that each sexual activity was a transfer before the veil. I am assuming from that that you mean that there was a transfer of energy for each sexual activity before the veil which indicates to me that a transfer doesn’t take place every time. Taking the case before the veil, would you trace the flow of energy that is transferred and tell me if that was the planned activity or a planned transfer by the designing Logos?

Ra: I am Ra. The path of energy transfer before the veiling during the sexual intercourse was that of the two entities possessed of green-ray capability. The awareness of all as Creator is that which opens the green energy center. Thusly there was no possibility of blockage due to the sure knowledge of each by each that each was the Creator. The transfers were weak due to the ease with which such transfers could take place between any two polarized entities during sexual intercourse.

I think if you can exercise this awareness with anyone then you are utilizing the green ray as best as possible. I think this is true whether it is your family, your friends or strangers.
