Divination can be done like that as well, you dont need cards or any tools actually, they just assist ... I actually do a 'type of divination (that isnt right every time
) that I dont use the cards for at all (and it is actually more accurate if I dont use the cards, but that is an aside)
- how the cards can help ; one way is , even if one learns all the 'lessons' contained within it is hard to remember them, Tarot symbolism has them coded within (in some decks). They are like an index system or a patterned form ... like a 'kata', in martial arts , in a way; if I want to teach (which requires that I remember) the 200 or so moves and applications of 'storming the fortress' I wouldnt have a chance, but the Pattern or Kata of storming the fortress has about 30 moves, I can learn that easily, each move triggers memory of the numerous applications, so by remembering the pattern I can have memory access much more. Most people, after a bit of training have no problem remembering a dozen or so patterns. Now the pattern assists memory by working through the physical body and becoming lodged in the motor skills.
In tarot it can be worked the same way but via visual images and their relationships and meanings being 'stored in the unconscious' - a vast reservoir and calculator that spits out results into the conscious. Each card contains a wealth of accessible info that I could never store alone in my consciousness ... regardless of the usage.
This isnt as amazing and 'over the top' as some have claimed (including here when I have talked about it before) ...the process can be looked at in greater detail from a few angles;
