The Juxtaposition Cross of Behavior is named here for Gate 10 and Gate 15. Its first article reads Gate 10 as behaviour that stays true to one's own nature rather than to expectation, now the more exposed gate, and Gate 15 as a love of humanity broad enough to embrace extremes, with no fixed rhythm. 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 cross draws one gate from each of the four.
Gate 10, the personality gate here, falls in the Quarter of Mutation, purpose fulfilled through transformation. Gate 15, its personality partner, falls in the Quarter of Civilization, purpose fulfilled through form. Behind them, Gate 18 falls in the Quarter of Duality, purpose fulfilled through bonding, and Gate 17 falls in the Quarter of Initiation, purpose fulfilled through mind.
So the true nature held to and the embraced extremes the first article reads on this cross's surface answer to the arcs of transformation and form, while the instinctive alertness to what is flawed and the mind forming opinions beneath them answer to the arcs of bonding and mind. The same pair, exchanged, is this cross's own reversal, the Juxtaposition Cross of Extremes, and, held instead in the Left Angle family, the Cross of Prevention, both orderings. The Right Angle family carries the same two gates too, as the Cross of the Vessel of Love, but only in this cross's own ordering; no Right Angle cross exists naming the reversed pair that Extremes carries. Four gates, four different Quarters, no pair sharing an arc: this cross draws its whole reading from every corner of the wheel's own purpose rather than concentrated in one.
