Gate 42, Growth: wind and thunder together, the hexagram of increase

Gate 42 is the place on Ra Uru Hu's wheel that carries hexagram 42, 益 Yì, increase: wind and thunder strengthening each other, what is given from above to those below. Human Design sets it in late Aries, in the Sacral centre, with one channel, Maturation, to gate 53 in the Root.

Meaning

Wind and thunder feed each other, and the hexagram is increase, the mirror of decrease: here what is above gives to what is below. Legge's Judgment says there will be advantage "in every movement which shall be undertaken", and that it will be advantageous even "to cross the great stream", the book's figure for a large undertaking. The Image is a lesson in self-correction: when the superior man sees good he moves towards it, and when he has faults he changes them.

Human Design places gate 42 from 20°45′ to 26°22′30″ Aries, in the Sacral centre, the motor the system ties to working and life-force energy. Its channel, which the school names Maturation, runs to gate 53 in the Root, the centre of pressure and drive in its terms; the pair is in the Sensing circuit of the Collective group.

The engine names the gate Growth. With its hexagram, we read it in our own words as increase that has to be carried through: energy that grows what has been started until it is complete. The tradition's increase is generous and active; its fifth line is sincere kindness that does not need to ask whether it will be thanked. Joined to gate 53, the hexagram of gradual progress, the goose moving step by step, the gate can be read as growth that comes in stages, each finished before the next is begun.

Opposite gate 42 on the wheel is gate 32, duration, and the school names the Right Angle Cross of Maya from 42 and 32 with 61 and 62. The I Ching's own pair for 42 is 41, decrease.

On the wheel

Gate 42 covers 5°37′30″ of the zodiac, from 20°45′ to 26°22′30″ Aries, the 15th gate counting from gate 41. In 2026 the Sun passes through it from 10 April to 16 April, and within a day of those dates in other years. Each of its six lines covers 56′15″:

  • Line 1: 20°45′ to 21°41′15″ Aries
  • Line 2: 21°41′15″ to 22°37′30″ Aries
  • Line 3: 22°37′30″ to 23°33′45″ Aries
  • Line 4: 23°33′45″ to 24°30′ Aries
  • Line 5: 24°30′ to 25°26′15″ Aries
  • Line 6: 25°26′15″ to 26°22′30″ Aries

In a chart the gate is active when any of the 26 positions falls in it, and the channel Maturation is defined only when gate 53 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 Maya (42/32 | 61/62), the Juxtaposition Cross of Completion (42/32 | 60/56) or the Left Angle Cross of Limitation (42/32 | 60/56). 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)
“Yî indicates that (in the state which it denotes) there will be advantage in every movement which shall be undertaken, that it will be advantageous (even) to cross the great stream.”
Human Design (Ra Uru Hu; the school)
Names the gate Growth and sets it in the Sacral centre, at one end of the channel Maturation. 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.

Growth that comes from finishing what has been started: read as the energy to see a cycle through, so that the next can begin.

Claims about it

  • Gate 42's place on the zodiac, 20°45′ to 26°22′30″ Aries, is where the I Ching itself puts hexagram 42.

    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 Sacral centre, where gate 42 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 42 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.
