Inductively, generally considering the explanations I gather that the type of assistance mentioned is akin to raising a family where each child can only be successfully guided and helped by the parents upon taking into consideration individual tendencies as well as past life instincts and even relationships.

That insightful knowledge is circumstantially shared by RishiDeva. Also, it seems that assistance from our perspective is not limited to making others comply with the end goals of the practice, but may actually even be very limited just on the karmic level of providing guidance and inspirations.

The aspirations of the individual receivers should and cannot ultimately be haphazardly violated. It is like adopting a teenager, one will only be able to contribute so much, and should be able to appreciate that level of assistance dispensed.  

The last paragraphs of the treatise are truly an amazement to behold!

In way my take away is that this represents the very inner mechanisms of salvation, even if generally defined. It is always said that the believer needs to follow the word of the prophet or liberator in earnest in order to guarantee their promises.

So the connection is a real perceptible energy thread running through individuals all the way down from the source-personality to the end followers. Only by application of the teachings can this connection to the source be factually achieved and maintained. Most religions propagate this format of adherence and exclusivity to the personal savior.
