"The experience of no need to find the necessary emolument."

[vervex]

Icipher, I cannot speak for everyone but my experience and understanding of service to others does not require sacrifice. When I love another, I am not losing anything and it does not cause me pain. Similarly, when I am helping another it is only an expression of this love I feel, an expression of who I am, truly. In my understanding, service can only be experienced as a sacrifice when one disregards a part of themselves or of another, when they experience an inner conflict with the service performed.

Perhaps we are having an arguments about semantics... Although sacrifice as a concept is highly acclaimed in some societies, its meaning is not positive and mostly self-destructive:

sacrifice
sac·ri·fice [sak-ruh-fahys]
noun
3. the surrender or destruction of something prized or desirable for the sake of something considered as having a higher or more pressing claim.
4. the thing so surrendered or devoted.
5. a loss incurred in selling something below its value.

The love of yourself AS part of oneness, as you term it, is loving all, including the individual self. It is not choosing to love others vs the self; it is loving both (and therefore realizing they are one). There is therefore no sacrifice but only all encompassing love and acceptance. And loving the self alone is indeed, as you have written, living in a paradigm of separation, an experience where only the individual self or an individual part of the self is loved. It is in this illusion of separation that perhaps an individual will experience sacrifice.

You finish your post very well with "universal love includes the self, it does not exclude the self in any way". I could not agree more and that is why I see no sacrifice in it whatsoever
