The Experience of the Spirit

[ricdaw]

I am unsure of the last sentence of this quote in regards to the english language and how and exactly what Ra meant by: "The Experience of the Spirit, that which you have called the Moon, is then, by far, the more manifest of influences upon the polarity of the adept." Can anyone offer an interpretation/explanation of this particular sentence?

I have only a partial understanding of this card, but I did have some practical spiritual experiences which I think may inform its meaning.
I think that one of the aspects of the card is to hint to the viewer that there is more to spirit than just some internal aspect of being.  The tower is the "aha!" of inspiration.  The Star inner faith.  But this card is an outside card and I think its primary lesson is to show that spirit is acting as profoundly on the external environment (things and events) as it works upon the inner environment.  What that dim and clouded moon suggests to me is that there is magic out there.  Real life magic.  It's not obvious (shadowy moonlight), it is protected (dogs), and it is possibly perilous to try and find it/learn it (scorpion, crawfish, crab).  The black magic (STS) is hard to find (no door on that dark pyramid) while white magic (STO) is easier to access (there is a door) but still it will take initiation and going into that huge pyramid structure.
But the magic, if found (either STO or STS magic) is so profound that it is a huge influence on polarity.
With some conscious mental thoughts and actions I was able to manifest a 40 minute winning streak gambling in Vegas.  It was an amazing experience because I had planned it to be a test of what I had learned about magical workings, so it was a lot more than winning some cash.  It was a validation that magic really worked.  (For New Agers, you would call it "you create your own reality.")  If I had had a mild tendency to STS, I'm pretty sure that the wonder and feedback of winning cash so easily would have sent me down the STS path.  (Woo hoo!  I'm gonna be rich!)  The "experience" of spirit that I actually had was profoundly influencial on me.  It was an experiment into the nature of reality and it proved (to me at least) that reality actually was subject to magical thinking.   "The Experience of the Spirit, that which you have called the Moon, is then, by far, the more manifest of influences upon the polarity of the adept." 
My gambling experiment was real and physical, but it was first and foremost an "experience of the spirit" because that is how I designed it to be. 
I think anyone that experiences psychic phenomena or hands-on healing or winning the lottery through prayer is someone who is likely to be influenced down one polarity or the other by such things in a huge way.  Reading Ra is quite moving, but putting the knowledge into practice is jaw dropping.
I think that's what the quote and the card speaks to:  spirit acting upon the environment is possible and powerful.
