JackofWands
I take JackofWands comment : " within the community of people who work with guides, there's no consensus regarding what those guides are " as more indicative of the modern 'spirit guides' movement than its relationship to tarot. It is certainly much newer than Tarot (in this 'spirit-guides' form ).
Yep. I wasn't referring to the idea that you presented later--namely, the possibility that entities one contacts during a Tarot reading are not what they purport to be--but simply to a lack of consensus in the more new-agey community regarding which entities can be contacted. Some see Tarot as a conduit for communicating with the dead, others for deities or angels. And to my eye, the simultaneous use of Tarot by various readers for all of these purposes and none shows that Tarot is not, in itself, linked to any external spiritual entity. If a reader chooses to use it in tandem with such, tant mieux, but there's no objective link.
In ceremonial magics of the evocative and invocative type (dealing with 'other' entities), there are certainly guidelines, laws, rules and practices to be able to determine 'what those guides are', their 'origins' , motivations, aims and effects .... BEFORE one 'lets them in'.
In the 'new-age' this baby seems to have been thrown out with the bath water; if it is an 'entity' and it is communicating with you, it is assumed all good, and of the 'highest spiritual import.
This wasn't where I was originally heading, but I like that you brought the discussion in this direction. I personally have never found cause to believe in supernatural entities, but if I were to try to work with one, I would only do so with bindings and protections up the wazoo. (This alone would make me want to avoid mixing evocation with Tarot, because a simple Lesser Ritual of the Pentagram wouldn't suffice for me, and I'm not sure I'd be willing to put in the effort necessary to consecrate my reading space after each client.) In addition, I think I would always maintain a healthy skepticism towards anything such an entity told me and anything it claimed to be.
Often, for some, these 'independent' entities or 'spirits' can be a 'split syndrome' from the psyche. The psyche itself (like the human body ) works in levels of importance and one system ruling or regulating another. A 'hierarchy' IS established, but it all needs to work holistically BUT be able to recognise malfunctions and 'foreign contaminates' .
I do quite like the psychological interpretation, and I think it's important to note that any manifestations of the unconscious mind in this sense are no less "real" in that they can still effect significant psychological change--positive or negative--in the mind from which they originated. (Access to objective external knowledge, on the other hand, has yet to get proved.) For this, I think that using spiritual entities in conjunction with Tarot reading can be useful and provide insight for a querent regardless of whence those entities originate (externally or internally). However, caution is still--in my humble opinion--important, because even the unconscious mind has as many nasties running around as all the demons in hell, and it's just as possible for a reader to dredge up negative influences as positive ones.
To boil that all down to the syrup ... one needs to know (from the magical perspective) what exactly is one dealing with, not accept things at 'face value' and create a clear distinction between any 'assisting spirit' and any ' malevolent spirit' (who, just like some people we have met, may be very good, subtle, or even unknowingly be masking their true intentions). In a tarot reading, I believe this can emerge as projecting one's psychological imbalances and syndromes into a reading ... usually not via the reading interpretations ... but by projecting their psychological associations into the reading ( divided by a subtle thin line in some cases)
I assumed that is the dynamic JackofWands is touching on ?
(sorry JofW if I missed the mark.)
Not where I was originally heading, but I agree with every word. Like I said, the original thought was much more simplistic--something along the lines of "I work with Athena and you work with the archangels, so objectively we can probably determine that Tarot itself is just as effectively used in the absence of either."
