The Left Angle Cross of Duality carries the same pair as the Juxtaposition Cross of Power with sun and earth exchanged, Gate 20 and Gate 34, two of the four Integration gates directly linked to each other. Human Design reads Gate 20, from Hexagram 20, Contemplation, sits in the Throat and is read as awareness and expression that occur now rather than in reflection, now the more exposed gate; and Gate 34, from Hexagram 34, Great Power, sits in the Sacral centre and is read as pure power, most potent simply being itself. 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.
Its design half is Gate 37 and Gate 40, the two ends of one channel, Community, also exchanged. Gate 37 sits in the Solar Plexus and is read as the warmth of family and friendship, specifically the bargain that holds a household together. Gate 40 sits in the Heart, or Will, centre and is read as the willpower to work, held against a real need for aloneness and rest.
Putting immediate awareness ahead of raw power changes what this cross puts forward first, while the same whole channel of domestic bargain and willed aloneness sits beneath it regardless of order. Both hexagrams are old texts; pairing them this way as a life direction dates from the system's founding in 1987.
