Basic principles of the spirit and the spirit in relation to the physical form. Fascinating!
I could go on and on about the fascinating philosophical concepts (in indeed helpful principles I'm able to actually use in my life).
In a nutshell, he gets down to the nitty-gritty on the goals of both a spirit as itself as well as in relation to the body/physical form and indeed the physical universe.
So it kind of covers both the spiritual nature of man and then that connection WITH the body (where then we have, "man" - ). Better understood if you listen to the lectures of course (and I can't make this review too long). Cheers and enjoy!
