The basic premise is that it's an experiment that Jen underwent with her family to rid of excess. Excess of food, clothing, wasting time on electronic devices, etc. She spent an entire month, four weeks, living by a strict rule of seven, 7 food choices, 7 articles of clothing, etc. And it wasn't just about what was absent in those months, it's about what filled the space instead. Since I haven't finished reading the entire book yet, I'm assuming that it's an exercise in recalibrating ones inner self as to what is truly important, about controlling quickly shifting priorities and encompassing only what is significant and meaningful. It's also about learning to do life with less and allowing what should be more in your life to emerge, naturally, organically, spirit-led.
