Service
We definitely need to serve other human beings and other sentient
beings. But we need to remember what serving them means. To serve
them is to guide them toward their greatest happiness and fulfillment,
which means to guide them toward their true nature and their function
in relation to this nature. This again is to serve the absolute
truth. We serve it by assisting its various manifestations to
attain the functions by which they can serve it, which is identical
with assisting their self-realization. In other words, when we
objectively understand and appreciate what service is, we realize
that there is no true difference between serving human beings
and serving God. (Inner Journey Home, pg 457)

Service and essence
We see that real service can only be done by somebody who knows
Essence. Selfless service means service not centered around the
false personality but centered around Essence. In Essence there
is no selfishness because there is no defensive separateness between
oneself and others. When an action serves one’s Essence,
it automatically serves the Essence of everybody else. (Essence,
pg 34)

Service is not a morally good action. It has nothing to do with
morality. Service is the useful and necessary work or action that
is needed for the realization and development of Essence, without
regard to boundaries of self and other. (Essence, pg 34)
