Maharaji himself is really a metaphor for the soul experience which resides within, and which he brings out.

First, there is no such thing as "the soul experience which resides within". That's just flowery bullshit which really means nothing.  Even more meaningless is the idea that Maharaji is either a "metaphor" for this illusional ... thing, or that he in any way brings it out. 

Many teachers seem to have the potential, it is not so rare at all.

You mean many "teachers" seem to be able to persuade people that they have this illusory potential to do this illusory act?  That, I'd agree with.

Many premies are quite happy with Prem because they appreciate his role as a soul opener or catalyst.

What is the problem, so long as they see the difference between the limited and contraversial Prem and the inner soul which is unlimited and exists freely of its own beautiful accord?

Not worth answering.
