The symbol cards offer you a way in to your imagination. The symbolism in the photo on each of the cards or what it is that attracts you in a photo is completely personal to you. What it will bring you when you start to work with it is entirely your own individual process, so allow yourself to be surprised.
In Chapter 2 of the Course Book there is a detailed explanation of how to work with the symbol cards, plus illustrations.
The Symbol Cards are part of the Imagination Toolkit 3.0. The set of 54 symbol cards (in high-quality print) can also be ordered as a separate set. Here you can see which 54 symbol cards are in the set.
