Well, I am not sure if I made it up or not. I may have seen it someplace, forgot and then just used that memory as a take off point from the decision spread/alternative spread I use. It looks like this. (xx's mark a card's spot) This spread relates to karmic lessons. I usually do a celtic spread when I just want to get an overview of a past life.

Hope all of this makes sense. Like I said, I am unsure where I got this spread and I may have just gotten it out of adapting another spread and just altered it to fit my purpose. I have had some wonderful readings with this spread, however, and recommend it.
