Left Angle Cross of Upheaval in Human Design

Its 4 gates

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

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.

Gate 38 · Root center

Standing firm

You push back against what seems unfair or false, especially when people's freedom is at stake.

Pick your fights: not every disagreement deserves a battle.

Gate 39 · Root center

Poking

Needling people a little to see what they are really made of is often your reflex.

For you, provoking has little to do with fighting, it is often a way to get attention, a bit like flirting.

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	17/18 \| 38/39	March 25 to March 29	Initiation	0.43%
2	18/17 \| 39/38	September 27 to October 2	Duality	0.56%

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 Initiation: the teaching links this quarter with the mind (understanding and making sense). Covers the Sun in gate 17.

Quarter of Duality: the teaching links this quarter with bonding (relating to another and passing things on). Covers the Sun in gate 18.

The 2-week test

Try this

For 14 days, keep a note with 5 columns: Take (gate 17), Touch-up (gate 18), Standing firm (gate 38), Poking (gate 39), plus a control column, Plain words (gate 23), 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 17 or 18 has one of these crosses, depending on their profile:
