An easy way to get the idea of the hexagram

Draw a crucifix. Draw a human over the figure of the crucifix. Draw a third eye in the brow.
Visualize the apex of the fire triangle being at the crown above the head, the brow eye, or the throat. The line will be the corresponding chest for the first two, and hips for the last.
The apex of the water triangle, will be the groin, or the heart. The line then will be the corresponding Hips or Shoulders.
The center will be the diaphragm or heart.
Then the planets listed will have a starting flame drawn from the left or right apex above to a flat line back up in a one-way direction
