The Right Angle Cross of the Sphinx, in this ordering, is named for Gate 13 and Gate 7 with the personality and design halves reversed from its better known ordering and the Sun and Earth exchanged within the pair itself. Its first article reads this as the listener placed ahead of the leader, carried consciously rather than behind the pair that names the cross's other orderings. What it does not trace is where the four gates sit on the wheel itself, the Human Design mandala's division of its sixty four gates into four Quarters, and by that measure this ordering still draws on exactly the same four Quarters as the rest of the family, one gate from each.
Gate 13, the personality gate here, falls in the Quarter of Initiation, purpose fulfilled through mind. Gate 7, its personality partner, falls in the Quarter of Duality, purpose fulfilled through bonding. Behind them, Gate 1 falls in the Quarter of Mutation, purpose fulfilled through transformation, and Gate 2 falls in the Quarter of Civilization, purpose fulfilled through form.
So the witness and the leadership the first article reads on this ordering's surface answer to the arcs of mind and bonding, while the creative expression and the receptive direction beneath them answer to the arcs of transformation and form, the same four arcs the rest of the Sphinx family draws on however its two pairs are assigned and ordered. Whichever gate carries the Sun and whichever pair is conscious, the wheel's own arithmetic supplies the same four Quarters.
