The Channel of Community joins the Solar Plexus centre to the Heart/Ego/Will centre through Gates 37 and 40, 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 37, The Family (Jia Ren). Wind issuing from fire, the outer life proceeding from the hearth. It is the household in its ordered roles, and words that carry weight because conduct backs them.
Hexagram 40, Deliverance (Xie). Thunder and rain breaking the storm's tension. It is release, knots untied and pardons issued, and the counsel to return to ordinary life as soon as deliverance is complete.
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.
