I Ching
The Book of Changes
Hold your question in mind. Three coins are tossed for each line, and the six lines are built from the bottom up.
Changing lines
How the oracle answers
Three coins are tossed for each line. The plain side counts three, the inscribed side two, so a line adds up to 6, 7, 8 or 9: a solid line for the odd numbers, a broken one for the even. Six lines, from the bottom up, make one of 64 hexagrams.
Six and nine are old lines, ready to turn into their opposites; they get their own texts and change the hexagram into a second one, where the situation is heading. Each coin here is one quantum random bit, 18 bits in all. The texts are our own, after the translations of James Legge (1882) and Richard Wilhelm (1924).
