Right Angle Cross of Tension in Human Design

Its 4 gates

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

Gate 21 · Heart center

In charge

Running your own patch suits you, without anyone checking each move you make.

You need a hand on practical matters: resources, territory, lifestyle and the group's decisions.

Gate 48 · Spleen center

Thirst to know

Getting to the bottom of things draws you in, with a nagging fear of never knowing enough.

You hold a deep well of solutions, which often shows only when someone comes to ask.

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 4 variants

The same name covers 4 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	21/48 \| 38/39	March 30 to April 4	Initiation	0.98%
2	39/38 \| 21/48	July 1 to July 6	Civilization	0.97%
3	48/21 \| 39/38	October 3 to October 7	Duality	1.2%
4	38/39 \| 48/21	December 31 to January 2	Mutation	0.98%

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: right angle

The angle comes from the profile alone: here, profiles 1/3, 1/4, 2/4, 2/5, 3/5, 3/6 and 4/6. The teaching describes a theme that plays out mostly along your own track: you live it for yourself first, and others cross it along the way. In our sample, 64.7% 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 21.

Quarter of Civilization: the teaching links this quarter with form (building and organizing shared life). Covers the Sun in gate 39.

Quarter of Duality: the teaching links this quarter with bonding (relating to another and passing things on). Covers the Sun in gate 48.

Quarter of Mutation: the teaching links this quarter with transformation (changing what already exists). Covers the Sun in gate 38.

The 2-week test

Try this

For 14 days, keep a note with 5 columns: In charge (gate 21), Thirst to know (gate 48), Standing firm (gate 38), Poking (gate 39), plus a control column, Standing out (gate 8), 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 21, 39, 48 or 38 has one of these crosses, depending on their profile:
