I had recently purchased the Playing Card Oracles book and I noticed several spreads provided. I am assuming that these spreads were created for the purpose of utilizing the full potential of the system. My understanding of the cards is that each card represents one week, but what if I just want to pull a card for the day? Just how flexible is this system? I know this may sound silly (and it probably is), but can this be used like any other playing card system with its spreads, like a past present, future gig? Thanks for putting up with my squared thinking.
