Gene Keys Profile · Key 55 of 64

Key 55, 豐 Fēng: thunder and lightning at full strength

Key 55 is 豐 Fēng, thunder above fire, the hexagram of abundance: the sun at noon, and the knowledge that noon is followed by afternoon. Our three words for its bands come from the line that sees the Dipper at midday, the line that brings the bright ones in, and the statement's counsel not to grieve but be like the sun at noon.

Meaning

豐 means abundant, full: a vessel heaped to the top. Thunder and lightning come together, movement and clarity at full strength. The statement of the hexagram says the king reaches this fullness, and counsels: do not grieve, be like the sun at midday. The commentary adds what everyone knows, that the sun past noon begins to set. Our gloss is fullness, the noon. The text is on the hexagram 55 page.

The Image speaks of deciding cases and punishments, which we leave to the text. Key 55 pairs with key 56, the traveller; its opposite on the wheel is key 59.

The three bands

The Shadow band, Gloom, is the second line, 日中見斗: at midday one sees the Dipper, the stars come out at noon, darkness that shuts out the light. The Gift band, Brilliance, is the fifth line, 來章: bringing in the brilliant ones, drawing out the bright in the people round about. The Siddhi band, Zenith, is the statement, 勿憂, 宜日中: do not grieve; be like the sun at midday, fullness enjoyed without fear of the turn.

The bands describe fullness darkened, shared and simply lived.

In a profile

Key 55 belongs to no particular row. It stands in a profile wherever one of the thirteen bodies stood between 0°07′30″ Pisces and 5°45′ Pisces at birth or at the design moment, and so it can fill any of the thirteen rows or the three further tags.

The Sun passes through it each year from about 19 to 24 February. People born then have key 55 as their Life's Work and its opposite, key 59, as their Evolution, the Earth's place. For people born about three months later, from about 19 to 24 May, it is the Radiance, where the Sun stood at the design moment.

Each of its six lines is 56′15″ wide. A position from 0°07′30″ Pisces is in line 1, read by our theme Foundation; one from 4°48′45″ Pisces is in line 6, Overview. Every key's lines take the same six themes of ours, and the line of a fast body like the Moon depends on the birth time to the hour.

How the schools read it

The Zhouyi, after Legge (1882)
Progress and development; the king reaches the point of abundance; no anxiety, but be like the sun at noon. The text in full is on the hexagram 55 page.
Human Design (Ra Uru Hu, 1987 onward)
Gate 55, in the Solar Plexus centre. The parent system gives the gate its own name and reading, which are Jovian Archive's and which we do not give here.
Richard Rudd, The Gene Keys (2009)
Key 55, read at three bands he calls the Shadow, the Gift and the Siddhi, each with a word of his own, under a chapter title of his own; we reproduce neither. He names key 59 its programming partner.
EsoTerrier
Fullness at its height: it sinks into gloom, darkness at noon, brings out the bright in the people around it, and at its peak enjoys the fullness without fear of the turn.

Claims about it

  • Key 55 is a code held in the genes, and contemplating it changes how they are expressed.

    unverified

    What the record shows: The central metaphor of Rudd's system, given by its author, not a finding. The profile is the positions of thirteen bodies at two moments, read on a 64-part wheel; no gene, codon or measurement of the body enters it.

  • Key 55 belongs to the Ring of Whirlwind, a chemical family in the body tied to histidine.

    unverified

    What the record shows: Rudd's grouping. His ring sizes follow the real number of codons per amino acid in the genetic code, but which hexagram goes with which codon is his own choice, and nothing in genetics links a hexagram to an amino acid.

  • The place of key 55 on the zodiac, 0°07′30″ Pisces to 5°45′ Pisces, is an old I Ching teaching.

    false

    What the record shows: The wheel is Ra Uru Hu's, fixed between 1987 and 1989 by turning Shao Yong's 11th-century circle of the hexagrams so that hexagram 41 begins at 2° Aquarius. No Chinese source we know ties the hexagrams to degrees of the zodiac.
