The Channel of Discovery joins the Sacral centre to the G/Identity centre through Gates 29 and 46, 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 29, The Abysmal (Kan). Water doubled, the ravine repeated. It is danger met twice over, and the counsel of water itself: sincerity that keeps flowing, filling every hollow on its way, passing through without being changed.
Hexagram 46, Pushing Upward (Sheng). Wood growing upward within the earth. It is unforced ascent, effort that rises step by step the way a tree does, invisible at first and then established.
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.
