Yi Jing, Oracle of the Moon

Xùn-Zhèn, Wind-Thunder

The great image says: Wind and Thunder (tempest) increase. When the noble one sees good, his rule is to improve, when there are transgressions, his rule is to reform.

  Xùn with Zhèn is a particularly favorable combination. One knows how to secure one's place in society to glory and splendor. Every action is without opposition. Thunder renews things but always from below, from the Earth, where the seeds and spirits reside. Thunder wakes up what is viable and has life force, plows under what is not, or is past.
  Xùn makes your Dao strong and focused, giving Zhen a clear direction for its energy. Imagine your goal and it will pull you along: with Xun and Zhen you renew and improve yourself and your environment.

  About the 3 lines of the trigrams and the spirit helpers:
  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, they listen to intentions, which can come from you, surroundings, or fate. Stationary helpers are part of the core meaning, they are your soul talking, but they also see the impossibilities or what is lacking at the moment. They reinforce the overall power of a reading.
