Traderdrew, I do use tarot cards as a focus for energy, they are a tool, they don't hold any value in and of themselves, you could use any thing as a focus. I like the symbolism and archetypes depicted in the tarot cards, and as I've mentioned before, they often have very beautiful artwork.
Reading and working with energy is like having an extra sense. One that is absolutly reliable when our other senses may fail. Energy cannot lie.
Spirits or gods,(all of them), are human manifestations of energy, they have no value or power unless we give them value and power.
