Relaxation

["danielestopinal" <djeestopinal@...>]

Greetings all,
I would like to know if it is advisable to do a relaxation meditation 
before beginning observing your thoughts in Lesson one. Or for that 
matter in any of the lessons. Maybe a progessive muscle relaxation. 
I noticed that Bardon presents relaxation in passing and only 
suggests taking a couple of deep breaths after being seated or prone 
in a comfortable chair or bed. Additionally, do any of you do a 
short ritual such as the Quabalistic cross and lesser banishing 
ritual of the pentagram before and after the work? 
Best regards
Dan
