STO and STS Mutually Exclusive?

7.15 ↥ Questioner: What is the density of the Orion group?

Ra: I am Ra. Like the Confederation, the densities of the mass consciousnesses which comprise that group are varied. There are a very few third density, a larger number of fourth density, a similarly large number of fifth density, and very few sixth-density entities comprising this organization. Their numbers are perhaps one-tenth ours at any point in the space/time continuum as the problem of spiritual entropy causes them to experience constant disintegration of their social memory complexes. Their power is the same as ours. The Law of One blinks neither at the light or the darkness, but is available for service to others and service to self. However, service to others results in service to self, thus preserving and further harmonizing the distortions of those entities seeking intelligent infinity through these disciplines.

Seconded. The way I would explain the bolded concept is that kindness is it's own reward.
