Six Doors 六门

Sixty-four hexagrams, six dimensions

Each hexagram is six lines, and each line is either yielding (yin) or firm (yang). Taken together, the sixty-four hexagrams arrange themselves like a six-dimensional cube: every hexagram touches exactly six neighbours — one for each single line that could flip.

Two ways to cast: coins and stalks

Three coins, cast six times, building the hexagram from the bottom line upward. The sum of each throw names the line: an old yin or old yang is a moving line, ripe to change; a young line rests as it is.

The instrument equally offers the older yarrow-stalk method. Both methods move a line with the same overall chance — one in four — but where the coins are even-handed, the stalks are not: under yarrow, yang is more inclined to move and yin to abide (old yang 3/16 against old yin 1/16). Choose either at the start of any cast.

Changing lines

The moving lines are where the reading breathes. Let them turn and the primary hexagram becomes a second — the state you are moving toward. The lines that change are the specific doors this cast has opened.

The six doors

Beside the classical reading of primary and relating hexagram, MANIFOLD GATES shows what the old texts could not: all six neighbours of your hexagram at once, each labelled with the line that would carry you there. The whole local weather of your moment, seen in a single view.
