How to read it

Each present number sits in its fixed cell. A corner (1, 3, 7, or 9) turns marked when it is isolated, meaning every cell that could connect it to the rest of the chart is empty. Filling any of those linking cells reconnects it, and the centre 5 reconnects every corner at once. When you fill a cell here, you are seeing a hypothetical: what a balancing name, or a consciously developed quality, would add. Your birth chart itself does not change.
