The Channel of Perfected Form joins the G/Identity centre to the Spleen centre through Gates 10 and 57, and both of those numbers are borrowed. They are positions in the King Wen sequence of the I Ching, the Chinese divinatory classic whose sixty-four hexagrams Human Design maps one to one onto the sixty-four gates of its bodygraph. Read as I Ching rather than as Human Design, the two numbers name two independent oracle texts.
Hexagram 10, Treading (Lu). Heaven above the joyous lake. Its image is treading on the tail of the tiger without being bitten: conduct, tact and good form carrying a person through real danger.
Hexagram 57, The Gentle (Xun). Wind doubled. It is penetration by what is gentle and continuous, the effect won by repetition that force cannot win at all.
The I Ching itself never sets these two hexagrams in a pair. Each stands alone in the sequence, consulted about a changing situation and answered in counsel that passes. The pairing is a construction of Ra Uru Hu's system, published from 1987, which fixes each hexagram to a position in a birth chart and reads the joined pair as a lasting trait of the person. The correspondence of number is real, and both hexagrams can be followed into their own entries in this atlas; the pairing, and the character read out of it, belong to the modern system alone.
