How Do STS's View Other Selves?

[anagogy]

STO can exist without STS, not the other way around.

I think the reason for that is because STO would be more accurately called "service to all selves", thus it is more balanced with respect to unity. STS may result in some small service to other selves, but it is not intentional and thus not enough for it to be balanced with respect to unity.

Given that seperation is an illusion, it is impossible to serve one to the exclusion of others. I'm inclined to believe everything is a service to all.

Well you're right, in my opinion. But there is intent to factor in. And while all may be a service, it is intentional service that is of most import when talking about polarity (imo).
