Astraea

My observation is that Sylvie doesn't so much change the traditional meanings of the cards, as she reassigns emphasis and uses some cards to give shades of meaning to traditional concepts (for example, Whips instead of Lilies for certain qualities of sexual experience, sometimes including abuse). She associates principles with pictures, and in the long run that is what we all do when we discover our particular ways of relating to the cards.

The no-layout method is where Sylvie's system differs most from the traditional Lenormand approach, but even so her card combinations are not incompatible with traditional card meanings.
