Using the "armor of light”

[tadeus]

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.

How do I understand this statement?

This is a really good question.
I would suppose that Ra has accidentally mixed up STO and STS here.

Before he has said:

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.

This is not logical too, since the forces cannot be balanced if only 1/10 can follow the STS.
Unless Ra means the collective approach / force of beings in the STS.

Those seeking intelligent infinity through the use of service to self create the same amount of power but, as we said, have constant difficulty because of the concept of separation which is implicit in the manifestations of the service to self which involve power over others. This weakens and eventually disintegrates the energy collected by such mind/body/spirit complexes who call the Orion group and the social memory complexes which comprise the Orion group.

I would say Ra is talking definitely here about the collective force of STS.

Thus, service to others preserves and harmonizes the distortions of all - the negative entity taking light, the positive entity giving light, and the positive entity surrendering to light inflowing from the Creator. 

This sounds possible.

It is "the right" of the negative entity to exercise and instruct this method of locking away light because the light that is available is infinite. 

Here i cannot agree, because this is complete different to just presenting a “other side of the case”.
