There appear to be two errors in the Tree of Life poster as shown in the back of such books as The Perfect Matrimony. Sephirah Netzach should be the Sphere of Venus and yet it shows the glyph of Mercury. Sephirah Hod should be the Sphere of Mercury and yet it shows the glyph of the Moon. Can anyone tell me if this is going to be corrected? Or, if it is not an error, explain why it is correct as shown?
