Gate 15, Extremes: the mountain hidden in the earth, the hexagram of modesty

Gate 15 is the place on Ra Uru Hu's wheel that carries hexagram 15, 謙 Qiān, modesty: a mountain set beneath the earth, height that does not show itself. Human Design places it across the turn of Gemini into Cancer, in the G centre, joined by the channel Rhythm to gate 5 in the Sacral.

Meaning

A mountain stands under the earth: something high that keeps itself low. The tradition reads the figure as modesty, and its six line texts are favourable from the first to the last. Legge's Judgment promises "progress and success"; the superior man, humble as it implies, carries his undertakings through. The Image gives the clearest picture of what modesty does: the superior man reduces what is too much and adds where there is too little, weighing things and making them even.

Human Design places gate 15 from 28°15′ Gemini to 3°52′30″ Cancer, in the G centre, which it ties to identity and direction. Its channel, which the school names Rhythm, runs to gate 5 in the Sacral, the motor it ties to working and life-force energy; the pair is in the Understanding circuit of the Collective group.

The engine's name for the gate is Extremes, which seems at first the opposite of modesty. The Image reconciles them. The modest person in the I Ching is the one who can see both extremes and bring them into balance, cutting the high and raising the low. We read the gate, in our own words, as range: an identity that is comfortable with very different paces and moods, and finds its measure across them rather than in a single one. Joined to gate 5, whose hexagram is waiting with meals taken in their time, it can be read as many rhythms held within one steady pattern.

Opposite gate 15 on the wheel is gate 10, treading on the tiger's tail. Both are in the G centre, and the school names a cross, the Vessel of Love, from the pair of them, read from either side. A cross is a name given to four positions in a chart, never a calling.

On the wheel

Gate 15 covers 5°37′30″ of the zodiac, from 28°15′ Gemini to 3°52′30″ Cancer, the 27th gate counting from gate 41. In 2026 the Sun passes through it from 19 June to 25 June, and within a day of those dates in other years. Each of its six lines covers 56′15″:

  • Line 1: 28°15′ to 29°11′15″ Gemini
  • Line 2: 29°11′15″ Gemini to 0°07′30″ Cancer
  • Line 3: 0°07′30″ to 1°03′45″ Cancer
  • Line 4: 1°03′45″ to 2°00′ Cancer
  • Line 5: 2°00′ to 2°56′15″ Cancer
  • Line 6: 2°56′15″ to 3°52′30″ Cancer

In a chart the gate is active when any of the 26 positions falls in it, and the channel Rhythm is defined only when gate 5 is active too, by either set.

When the Personality Sun is in this gate, the school's table names the cross by the angle of the profile: the Right Angle Cross of the Vessel of Love (15/10 | 25/46), the Juxtaposition Cross of Extremes (15/10 | 17/18) or the Left Angle Cross of Prevention (15/10 | 17/18). The four numbers are the Personality Sun and Earth, then the Design Sun and Earth. We give the names only.

How the schools read it

The I Ching, in Legge's translation (1882)
“Khien indicates progress and success. The superior man, (being humble as it implies), will have a (good) issue (to his undertakings).”
Human Design (Ra Uru Hu; the school)
Names the gate Extremes and sets it in the G centre, at one end of the channel Rhythm. Its descriptions of the gate and its six lines are in Ra Uru Hu's books, in copyright; we do not quote or paraphrase them.
The independent schools
Zeno Dickson and Chaitanyo Taschler, Chetan Parkyn, Karen Curry Parker and later teachers compute the same gate at the same place, and read it in their own words.
EsoTerrier
Modesty as a way of levelling: read as a sense of measure that can hold many rhythms at once, the high and the low together.

Claims about it

  • Gate 15's place on the zodiac, 28°15′ Gemini to 3°52′30″ Cancer, is where the I Ching itself puts hexagram 15.

    false

    What the record shows: The wheel is Ra Uru Hu's arrangement: Shao Yong's 11th-century circle of the 64, rotated so that hexagram 41 starts at 2° Aquarius. No Chinese source ties a hexagram to degrees of the zodiac.

  • The G centre, where gate 15 sits, is an organ or gland, and the gate tells something about the body.

    unverified

    What the record shows: The centre's name is a name. The schools' pairing of the centres with organs and glands, taken from the chakra books of the 1920s, has no physiological correspondence that anyone has shown, and we never read a gate or a centre as the body or its health.

  • Gate 15 is one of the 64 codons of the genetic code, so it marks something in a person's genes.

    false

    What the record shows: Both sets have 64 members because both are built from a small alphabet in groups: two kinds of line in six places, four bases in three. Nothing beyond the count matches.
