The Juxtaposition Cross of Serendipity carries the same four gates as the Left Angle Cross of Healing, held here in the fixed Juxtaposition family instead. Human Design reads Gate 46, from Hexagram 46, Pushing Upward, as a love of the body and a knack for arriving in the right place at the right time, the trait practitioners call serendipity, seated in the G, or Identity, centre; and Gate 25, from Hexagram 25, Innocence, as an innocence that places universal love above particular attachment, also seated in the G, or Identity, centre. Juxtaposition Crosses stand apart from the other two families, tied only to the four line one profile, and are read as the most fixed direction the system names.
Its design half is Gate 52 and Gate 58, both seated in the Root, unchanged from the Cross of Healing's own design half. Gate 52 is read as a stillness that concentrates rather than releases, holding a person still long enough for perspective to form. Gate 58 is read as vitality and the joy of being alive, expressed as an urge to improve whatever is at hand.
Where the Left Angle reading serves something handed back by circumstance, the Juxtaposition reading holds the same love of the body and Root stillness as fixed to the four line one profile rather than assigned by fate. The hexagrams are ancient; grouping them into one fixed cross is the modern system's own construction.
