The Left Angle Cross of Refinement is named for Gate 33 and Gate 19. Human Design reads Gate 33, from Hexagram 33, Retreat, as the need to withdraw and hold an experience privately before telling it, and Gate 19, from Hexagram 19, Approach, as sensitivity to what a community needs, materially and physically. It belongs to the Left Angle family, read as transpersonal, a direction practitioners describe as answering less to personal choice than to what circumstance hands the individual, which the cross reads as a slow refinement of what is withdrawn and later offered back.
Its design half is Gate 2 and Gate 1, both in the G, or Identity, centre. Gate 2 is read as the receptive sense of where a life is meant to go, pairing elsewhere with Gate 14 in the channel of the Beat. Gate 1 is read as the urge to give an individual creative direction some outward form, pairing with Gate 8 in the channel of Inspiration.
So a chart carrying this cross withdraws material sensed from a community, Gate 19, holds it privately, Gate 33, while an Identity centre beneath decides its direction and its form. The hexagrams are ancient; joining withdrawal, need and identity into one reading is the modern system's own construction.
