Left Angle Cross of Prevention (15/10)

The Left Angle Cross of Prevention is named for Gate 15 and Gate 10, both seated in the G, or Identity, centre. Human Design reads Gate 15, from Hexagram 15, Modesty, as a love of humanity broad enough to embrace extremes, with no fixed rhythm of its own, and Gate 10, from Hexagram 10, Treading, as behaviour that stays true to one's own nature rather than to expectation. 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 preventing harm on behalf of others rather than for oneself.

Its design half is Gate 17 and Gate 18. Gate 17 sits in the Ajna and is read as the forming of opinions that want to be organised and offered to others; elsewhere it pairs with Gate 62 in the channel of Acceptance. Gate 18 sits in the Spleen and is read as an instinctive alertness to what is flawed and could be set right; it pairs with Gate 58 in the channel of Judgement.

So the cross joins a wide, extremity tolerant humanity, Gate 15, to conduct true to one's own nature, Gate 10, while beneath it opinions formed in the Ajna, Gate 17, meet a splenic instinct for what needs correcting, Gate 18. The hexagrams are ancient; joining them into one incarnation cross is the modern system's own construction.

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

The Left Angle Cross of Prevention is named for Gate 15 and Gate 10, and its first article traces both gates, together with their design counterparts, Gate 17 and Gate 18, to a tolerant humanity meeting a corrective instinct. What it does not trace is where the four gates sit on the wheel itself, the Human Design mandala's division of its sixty four gates into four Quarters, and by that measure this cross draws one gate from each of the four.

Gate 15, the personality gate, falls in the Quarter of Civilization, purpose fulfilled through form. Gate 10, its personality partner, falls in the Quarter of Mutation, purpose fulfilled through transformation. Behind them, Gate 17 falls in the Quarter of Initiation, purpose fulfilled through mind, and Gate 18 falls in the Quarter of Duality, purpose fulfilled through bonding.

So the tolerance and self-regard the first article reads on this cross's surface answer to the arcs of form and transformation, while the formed opinion and the corrective instinct beneath them answer to the arcs of mind and bonding. Four gates, four different Quarters, no pair sharing an arc: the prevention this cross is named for is drawn from every corner of the wheel's own purpose rather than concentrated in one.
