Well, because Ra is narrow-band and had to blend their own distortions with Carla's. This suggests to me that Carla also had to be close enough to Ra's distortion for them to be able to accommodate the transfer. They mention numerous times that the unique efficiency of the channeling group was due to their intense dedication towards service to others, especially in regards to eachother and in their seeking of the Law of One. So I absolutely feel that the orientation and polarity of the individuals in the group would play a role in the ability to channel Ra.
Abstinence meaning refraining from a behaviour.
Both polarities were possible before the veil. The Logos had it in its plan from the start and the potential was always there. The veil just brought in to sharp awareness what was already latent. Maybe there were no harvestable entities of service to self, but that doesn't mean service to self polarity didn't exist at all. It may have just been so subtle as to be unnoticed until the amplifications of catalyst via the veil.
You're right, it wasn't accurate to say they didn't exist, more to say that it was 'monochrome' in the way Ra suggests with more primitive tribes.
