The Right Angle Cross of Penetration, named here for Gate 53 and Gate 54 rather than Gate 51 and Gate 57, carries the pressure to begin ahead of ambition on its exposed Root surface. Its first article reads Gate 53 as the pressure to begin, an impulse that starts new cycles and often has no interest in seeing them through, and Gate 54 as ambition, the drive to rise and transform one's material circumstances. 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 53, the personality gate here, falls in the Quarter of Civilization, purpose fulfilled through form. Gate 54, its personality partner, falls in the Quarter of Mutation, purpose fulfilled through transformation. Behind them, Gate 51 falls in the Quarter of Initiation, purpose fulfilled through mind, and Gate 57 falls in the Quarter of Duality, purpose fulfilled through bonding.
So the pressure to begin and the rising ambition the first article reads on this ordering's surface answer to the arcs of form and transformation, while the startling courage and the quiet intuition beneath them answer to the arcs of mind and bonding, the same four arcs the rest of the Penetration family draws on however its two pairs are assigned and ordered. Named for beginning rather than for shock, this variant still rests on the wheel's own arithmetic of one gate from each Quarter. With this fourth arrangement in place, every ordering of the Penetration family now carries the same reading.
