The Channel of Judgment joins the Spleen centre to the Root centre through Gates 18 and 58, 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 18, Work on the Decayed (Gu). Wind trapped at the foot of the mountain. Its image is decay bred by neglect, and its work is repair: deliberation before the new start, and care after it.
Hexagram 58, The Joyous (Dui). The lake doubled. It is joy exchanged, friends encouraging one another in practice, and gladness that endures because it stands on inner firmness.
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.
