Thunder AKA The Arousing

Symbol of enlightenment in the bottom position of a hexagram, and awareness when in the top position of a hexagram. One of the six 'mixed' trigrams, symbolic of the interaction of degrees of yin and yang. In the template it is representative of expansive binding and thus an overall bias to making distinctions through the determination of dynamic relationships between inner and outer.

In the Myers-Briggs/Keirsey systems of persona classification it is linked to XNTP/Engineers and is mostly concerned with solution seeking through relational analysis. (e.g. Inventors, Architects, Philosophers)

The numeric link is to complex numbers (transitions and transformations).
