Left Angle Cross of Prevention in Human Design

Its 4 gates

In Ra Uru Hu’s teaching, the name “Left Angle Cross of Prevention” sums up how these 4 gates meet. Read them one by one: that is where the concrete content sits.

Gate 15 · G center

Shifting rhythms

Your rhythms vary a lot from one period to the next, and you are easygoing with people unlike you.

You swing between action and withdrawal, company and solitude, with no predictable pattern.

Gate 10 · G center

At ease

Staying true to how you are matters, even when not everyone likes it.

You love your life as it comes, challenges included, and follow your convictions even when others find them thin.

Gate 17 · Ajna center

Take

An opinion forms quickly in your head about how things ought to go.

Your view serves the group; it gains value when people discuss it and correct it together.

Gate 18 · Spleen center

Touch-up

What is off in a system jumps out at you, and you want to set it straight.

You question inherited rules, especially the patterns handed down by your parents.

Its 2 variants

The same name covers 2 Sun gates. The 4 gates stay the same; only their places change. Your variant depends on the gate of your birth Sun.

Variant	Gates	Birth Sun	Quarter	Frequency
1	15/10 \| 17/18	June 20 to June 24	Civilization	0.47%
2	10/15 \| 18/17	December 20 to December 25	Mutation	0.54%

First two numbers: Sun and Earth at your birth. Last two: Sun and Earth about 88 days earlier, the part of the chart called the “design”. Birth Sun dates are for a typical year, give or take a day.

The angle: left angle

The angle comes from the profile alone: here, profiles 5/1, 5/2, 6/2 and 6/3. The teaching describes a theme that plays out mostly through encounters: other people are its main ground. In our sample, 33.1% of charts have a cross with this angle. The 3 angles explained.

The quarters

Quarter of Civilization: the teaching links this quarter with form (building and organizing shared life). Covers the Sun in gate 15.

Quarter of Mutation: the teaching links this quarter with transformation (changing what already exists). Covers the Sun in gate 10.

The 2-week test

Try this

For 14 days, keep a note with 5 columns: Shifting rhythms (gate 15), At ease (gate 10), Take (gate 17), Touch-up (gate 18), plus a control column, Pathfinder (gate 7), which is not part of this cross. Each evening, reread the line for each gate above and tick the ones that described a real moment of your day, with a word on what happened. After 2 weeks, count the ticks. According to the teaching, the gate of your birth Sun should come out on top. If the 4 cross columns do not clearly beat the control column, give this name little weight.

Same Sun gates, other angles

Someone born with the Sun in gate 15 or 10 has one of these crosses, depending on their profile:
