Prem Rawat is extremely deluded and believes he is the Perfect Master, but he is also not stupid.  I think he knows that the "keys" won't work because he has been through this many times, and none of it ever works, in the sense that it attracts large numbers of people to him and "his message."

I rather think that it is all done to give the premies something to do, to keep them (or some of them) involved, and give them something to give money t, all in an attempt to keep people donating to him, so that he can keep his lifestyle financed.

So, it may be mostly pretense.  I could be very wrong about this, maybe Rawat really does believe this is the breakthrough, but I have a very hard time believing that.
