How do you fill in/exactly what is the lower part of this beautifully crafted chart (the pyramid at the bottom)? Ive no idea what to do with it, please help!
The grid is for writing in the aspects between the planets. Blank charts always had room for an aspect grid and other info, such as number of planets in elements and modes. Glad you like the chart!
