Led Zeppelin III #6 Gallows Pole (backward lyrics in red)

The 1970 release of album III, which was recorded in part at Headley Grange in Hampshire, is a mile stone in terms of back masked content:

- Song #6 (Gallows Pole | https://www.youtube.com/watch?v=LpGDTqHM5sw&t=3m ) contains the phrase "Ropes are all I contribute Going FAZI"

- Song #8 (That’s the Way | https://www.youtube.com/watch?v=CJcVxdAkOwo&t=1m42s ) contains the phrase "It's an order here with FAZI He seeked out with Man made goodwill".
The only explanation I have been able to conclude from searching about this name FAZI, is that it is privy to Led Zeppelin and possibly the name of an entity similar to Aiwass. It's also possible many of the lyrics were dictated to Led Zeppelin by FAZI in the same manner that AIWASS dictated to Crowley. However taking a wild guess, I think it's a portmanteau of FAUST and NAZI.
