Changing Lines in the I Ching

Lines with values 6 and 9 are moving. Transforming them produces the resulting hexagram; when several lines move, an explicitly selected reading school determines which texts govern.

Primary hexagram

This is the initial pattern of the six obtained lines before 6 and 9 transform. Its role in the reading depends on the registered reading policy, not a hidden interface rule.

  • Line 1 is at the bottom.
  • Line 6 is at the top.
  • The hexagram number comes from a separate received-sequence map.

Changing lines

6 is old yin and 9 is old yang; both are moving lines. The number of moving lines does not invalidate a cast: for 0–6 changes, a previously named reading school is applied.

  • 6: yin → yang.
  • 9: yang → yin.
  • With multiple lines, the site does not improvise a governing line.

Resulting hexagram

It is computed mechanically after all 6s and 9s are transformed together. It is a derived pattern of the consultation, not an automatically guaranteed future.

  • With 0 moving lines the pattern does not change.
  • With 1–6 changes, only 6s and 9s transform.
  • The reading policy determines which texts are read.

Checklist

  • I know which method produced the 6/7/8/9 values.
  • I can see all moving lines and the resulting pattern.
  • I know which reading school selected the texts being read.

Boundaries

  • If the answer creates panic, stop and return to facts.
  • Do not make risky decisions based only on a line.

FAQ

Which hexagram matters more?

There is no single universal rule for every combination of moving lines. OmenHall must show the selected reading school and apply that school without conflating it with the cast itself.

What if many lines change?

Do not discard the cast or invent a governing text after the fact. Apply the previously selected reading policy, such as the registered Zhu Xi policy or the transparent modern all-moving-lines policy.
