The service that the disciple can offer the Master is not only linked with the universal cause of humanity but is one of the most potent means of bringing the disciple nearer his spiritual goal.
When the disciple’s service is spontaneous, whole-hearted, selfless, and unconditional, it brings him more spiritual benefit than can ever come by any other means.
Serving the Master is a joy for the disciple, even when it means an ordeal that tries his body or mind.
Service offered under conditions of discomfort or inconvenience is a test of the disciple’s devotion. The more trying such service becomes, the more welcome it is for the disciple. And as he voluntarily accepts physical and mental suffering in his devoted service to the Master, he experiences the bliss of spiritual fulfillment.
