I don't think it is an actual critical, historical, known Satanic text.
I have an extensive library and sources for research which include known and unknown libraries and collections worldwide. This text has never come up anywhere nor from any connections I have. Methinks it is made AND made up by the source material from the video creators.
Rasobel = Lesobar
It is a play on Lucifer, which is hinted within the video itself, referring to Black Masses and Liturgics. A common play on the Lord's Prayer in reverse, etc. In any case, I was not able to find the text in question short of spending $10 which I really have no desire to. I have enough Satanic literature which I only utilize to cross reference with anyways.
iNormal,
I suggest the works of Peter H. Gilmore, Nate Leved, Michael Aquino, Nagasiva Yronwode, Patrick Gaffiero and Michael W. Ford (though he is a Luciferian). A lot of Youtube content is questionable when made into videos using graphics content for footage with a voice over.
