The Channel of Openness joins the Throat centre to the Solar Plexus centre through Gates 12 and 22, 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 12, Standstill (Pi). Heaven withdrawing upward while earth sinks away below, the two no longer meeting. It is estrangement and stagnation, the inverse of Peace, a time when the inferior advance and the great withdraw.
Hexagram 22, Grace (Bi). Fire illuminating the foot of the mountain. It is adornment, form gracing substance, and its own judgment keeps it modest: grace brings success in small matters, for ornament is not foundation.
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.
