But now coming to the question: who must work for the Cause and who need not work for the Cause? and the answer is that we all need not work for the Cause; only those who will work for the Cause must work for the Cause. For the service that a worker will render to the Cause must not be rendered in this spirit that: we return to Murshid, or we render to Murshid a service in return for what we receive from him. Because that will be a business. It will mean Murshid helps his pupils to the light on condition that they will work for the Cause. There must be these two things separate. The idea that we receive a spiritual help on the path of truth is something priceless, that we must never think of returning in any form, for it cannot be returned. And as long as a mureed will not value it to this extent he will not be able to be fully benefitted by it.
