Service

Service is another word for the utilization of soul force for the good of the group. Where this impulse is lacking, energy may pour into the bodies, but - lacking use and finding no outlet - will tend to over-stimulate the centers, and produce conditions disastrous to the neophyte. Assimilation and elimination are laws of the soul life as well as of the physical life, and when this simple law is disregarded serious consequences will follow as inevitably as in the physical body.
