The Right Angle Cross of Service is named here for Gate 17 and Gate 18, opinion exposed ahead of correction. Its first article reads Gate 17 as logical opinions organised and offered to others, and Gate 18 as an alertness to what is flawed and could be set right. 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 17, the personality gate, falls in the Quarter of Initiation, purpose fulfilled through mind. Gate 18, its personality partner, falls in the Quarter of Duality, purpose fulfilled through bonding. Behind them, Gate 58 falls in the Quarter of Mutation, purpose fulfilled through transformation, and Gate 52 falls in the Quarter of Civilization, purpose fulfilled through form.
So the formed opinion and the corrective alertness the first article reads on this cross's surface answer to the arcs of mind and bonding, while the restless urge to improve and the held stillness beneath them answer to the arcs of transformation and form. Four gates, four different Quarters, no pair sharing an arc: the Cross of Service this entity is named for draws its whole reading from every corner of the wheel's own purpose rather than concentrated in one. With this fourth arrangement in place, every role rotation of Service's two gate pairs shares the same wheel wide spread.
