3-4-trigrams

Zhèn-Xùn, Thunder-Wind

When Zhèn activates Xùn, the trigram of wind and wood, they make the branches sway from the roots, they make all things act from their core. It is the relentless movement that follows fate and finds its destiny. Whenever you stray from your birthright, you have the opportunity to retrace your steps and find the right direction again. Walking your dao means following your essential path without deviating, even if it takes you along winding roads.

There will be powerful people who are ignorant, indifferent, and non-conforming. One encounters much resistance in one's life.

The outcome

The middle line (Man-line) shows the outcome.

   Each line, active or at rest, summons one of the 8 trigrams as a Helper. For an activated line: telling you what you need - or about a problem area or something to avoid.
  For a stationary line: this is what you already have or do or what you don't need. Often we just need a reminder of our abilities. Or it could be what you wish or fear - but will not happen.
  Active lines are the helpers to change things. Stationary helpers are part of the core meaning, they are your soul talking. They reinforce the overall power of a reading.
   Advice for the initiative: Li, Fire, with her power to discern and create order.
   Advice for the subject: Kun, Earth, with her ability to nurture and concretize.
   Advice for the outcome: Dui, Lake, with her ability to resonate and persuade.
