In an earlier post, using a tarot journal as your own personal dictionary was mentioned. This is more helpful than you can imagine. By doing this, you refer back to your own thoughts rather than someone else's opinion. And eventually, you will only look back occasionally. Also, you can add to your dictionary as you learn more about an individual card.
An entry may look something like this:
Keywords - leap of faith, innocence
The Fool suggests taking a blind leap of faith, having courage and taking risks.
In the reversed position, The Fool can mean a failure to follow your instincts, but it can also warn against taking unnecessary risks.
Yes, you could add many more fields to your entry, like numerical values, symbolism, and such. Feel free to do so, if you feel you need it to better understand the card. The point is to get everything in one spot to make referring back easier and more convenient. Remember to allow room for expansion on your thoughts for each card.
What fields do you have in your tarot dictionary journal? What fields do you think are actually needed?
