The Right Angle Cross of Explanation completes its four role arrangements with this ordering, Gate 49 and Gate 4 exposed, a principle ahead of an offered answer. Its first article reads Gate 49 as the sense of what is acceptable, deciding whether an arrangement continues or is broken off, and Gate 4 as the mental habit of offering answers and hypotheses to questions still open. 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 49, the personality gate here, falls in the Quarter of Initiation, purpose fulfilled through mind. Gate 4, its personality partner, falls in the Quarter of Duality, purpose fulfilled through bonding. Behind them, Gate 43 falls in the Quarter of Mutation, purpose fulfilled through transformation, and Gate 23 falls in the Quarter of Civilization, purpose fulfilled through form.
So the judgment of what is acceptable and the offered answer the first article reads on this ordering's surface answer to the arcs of mind and bonding, while the sealed insight and its telling beneath them answer to the arcs of transformation and form, the same four arcs the rest of the Explanation family draws on however its two pairs are assigned to personality and design. With this fourth arrangement in place, every role rotation of Explanation's two gate pairs shares the same wheel wide spread, one gate from each Quarter regardless of order.
