This Left Angle Cross of Masks is named for Gate 7 and Gate 13 rather than Gate 13 and Gate 7, the leader placed ahead of the listener. Human Design reads Gate 7, from Hexagram 7, The Army, as the self cast in the role of leader, guiding others toward a shared future without necessarily holding formal power, and Gate 13, from Hexagram 13, Fellowship, as the one to whom others tell their stories and confide the past. It sits in the Left Angle family, and Human Design reads that group as outward facing, less a chosen plan than a role other people keep handing back.
Behind that pair, Gate 23 and Gate 43 form the design half, exchanged from the counterpart cross. Gate 23 sits in the Throat and is read as assimilation, the voice that turns a strange individual insight into language other people can actually take in; elsewhere it pairs with Gate 43 in the channel of Structuring. Gate 43 sits in the Ajna and is read as individual insight, a sudden inner knowing that arrives whole and cannot easily be explained; it pairs with Gate 23 in that same channel.
Placing the leader ahead of the listener changes what this variant of the Masks cross puts forward, guidance before witness, though the same four gates run beneath every ordering in the family. The hexagrams are ancient; the four orderings that name four separate crosses belong entirely to the modern system.
