I remember this piece of writing being discussed here a while ago, may be a year or so back. And from what I recall, I think it was determined that this was not written by Rawat, but sourced elsewhere by him (although from where I cannot remember). He just ripped it off. Sorry for my vagueness - may be someone else can remember where it did originally come from, or even if that was established. Reading this 'letter' now makes me feel quite ill! Yet when I read this in the 80's I was awe-struck. Shows how cultified I was back then. Shows how free I am now! Now I can see how the letter aims to create an emotional and psychological dependence of the reader upon the writer/guru/lotu.
Thank goodness that by the Grace of Doubt and with the help of EPO & F8, I am now free!
