The Right Angle Cross of Explanation carries the same channel as the earlier Cross of Explanation with sun and earth exchanged, Gate 23 and Gate 43, the two ends of Structuring. Human Design reads Gate 23, from Hexagram 23, Splitting Apart, sitting in the Throat, as the voice that turns a strange individual insight into shared language, now the more exposed gate; and Gate 43, from Hexagram 43, Breakthrough, sitting in the Ajna, as the sudden inner knowing behind it. It sits in the Right Angle family, the most populous of the three, and Human Design reads that family as steered chiefly by personal choice.
Its design half is Gate 49 and Gate 4, also exchanged. Gate 49 sits in the Solar Plexus and is read as principle, the sense of what is acceptable that decides whether an arrangement continues; it pairs with Gate 19 in the channel of Synthesis. Gate 4 sits in the Ajna and is read as the mental habit of offering answers and hypotheses to questions still open; it pairs with Gate 63 in the channel of Logic.
Putting the telling ahead of the knowing changes what this cross puts forward first, while the same sense of what is acceptable and habit of hypothesis sit beneath it regardless of order. The same channel, unreversed, is also another Cross of Explanation, and the same two gate pairs with roles exchanged form a third arrangement of the same set. Both hexagrams are old texts; pairing them this way as a life direction dates from the system's founding in 1987.
