The Channel of Transformation joins the Spleen centre to the Root centre through Gates 32 and 54, 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 32, Duration (Heng). Thunder and wind, movement paired with penetration. It is endurance, the constancy of a long union, standing firm in one's course without rigidity.
Hexagram 54, The Marrying Maiden (Gui Mei). Thunder stirring the lake. It concerns entry into relation on unequal terms, affection within a subordinate place, and the tact such a position demands.
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.
