I am not sure who uploaded these PDFs. All I know is I wish the whole of humanity would read these works. To say that reading them has changed my life would be a most magnificent lie. To detractors of these works, and skeptics (as I was one previously), look up the Wikipedia article and simply read the work. I do not necessarily support the publisher of these works now (the company/person who holds the copyright), and I do not believe anyone should have to pay for a divinely inspired piece of literature.
Pray to the Trinity and to Mother Mary for the salvation of your soul and the souls of all.
