Nuclear Hexagram

A nuclear hexagram reuses one diagram rather than making another cast. Its overlapping selection of the middle four lines supplies a supplementary internal or process-oriented image in methods that use it. Middle first means line position, not automatic evidence of a hidden event or dated phase.

Omit the bottom and top lines; take 2/3/4 below and 3/4/5 above. Original lines three and four are each used twice. Mei Hua Yi Shu records this extraction method. Nuclear imagery is a separate layer from Najia Self/Other positions and relationship assignments.

Zhun is yang/yin/yin/yin/yang/yin from bottom to top. Lines 2/3/4 give Kun, and 3/4/5 Gen, producing Bo, Mountain over Earth. Nuclear extraction selects positions; a relating hexagram flips moving lines. Mei Hua Yi Shu gives a special instruction to use the changed hexagram for Qian and Kun, so state that convention when applying it.

Continue Zhun giving nuclear Bo: original lines one and six are omitted, and two through five recombined. Changing only Zhun’s bottom line leaves the middle-line extraction unchanged even though the changed hexagram differs. Nuclear extraction and moving-line transformation therefore supply different information.

A method using nuclear imagery should explain the primary relationship, specify what imagery the nuclear structure adds, then return to actual changes. In a Najia-centered reading, distinguish this optional method from the core Self/Other and relationship calculations.
