The Left Angle Cross of Spirit carries the same pair as the earlier Cross of Spirit with sun and earth exchanged, Gate 55 and Gate 59. Human Design reads Gate 55, from Hexagram 55, Abundance, sits in the Solar Plexus and is read as an emotional weather swinging between melancholy and abundance, now the more exposed gate; and Gate 59, from Hexagram 59, Dispersion, sits in the Sacral centre and is read as the energy that breaks down barriers between people. 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 9 and Gate 16, also exchanged. Gate 9 sits in the Sacral centre and is read as the capacity to attend to small details a larger idea depends on; it pairs with Gate 52 in the channel of Concentration. Gate 16 sits in the Throat and is read as enthusiasm refined by repetition into real skill; it pairs with Gate 48 in the channel of the Wavelength.
Putting a swinging mood ahead of dissolved barriers changes what this cross puts forward first, while the same attention to detail and repetition-proven enthusiasm sit beneath it regardless of order. The numbers are inherited from the I Ching; reading them as one cross belongs to the modern reading, not the classical one.
