The Left Angle Cross of Defiance, named here as Gate 2 and Gate 1, carries the same pair as its counterpart with sun and earth exchanged. Human Design reads Gate 2, from Hexagram 2, The Receptive, as the receptive sense of where a life is meant to go, now the more exposed gate, and Gate 1, from Hexagram 1, The Creative, as the urge to give that direction some individual, creative form. 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, which gives the cross its name.
Its design half is Gate 49 and Gate 4. Gate 49 sits in the Solar Plexus and is read as principle, the sense of what is acceptable that decides whether an arrangement continues; elsewhere it pairs with Gate 19 in the channel of Synthesis. Gate 4 sits in the Ajna and is read as the mind's habit of proposing answers to open questions; it pairs with Gate 63 in the channel of Logic.
Exchanging which gate carries the Sun puts direction ahead of expression, while the design half keeps the same Solar Plexus judgment answering to the same questioning mind. The hexagrams are old texts; the reversal and the Left Angle reading both belong to the system founded in 1987.
