Yi Jing, Oracle of the Moon

Xùn-Zhèn, Wind-Thunder

    

  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, plows under what is not.
  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.

The initiative

    
The top line (Heaven-line) shows the change of the focus or initiative.
变上爻为坎, 风入水面, 为浪为波, 漂泊劳碌,
小 人尤畏, 亦为混浊之乖, 少全清节,
有 岸覆舟之虞。
When the upper line changes, Wind activates Water. The wind penetrates the surface of the water, making waves and swells. Busy activity but drifting aimlessly.
Little people are very fearful and there is also the shrewdness of corruption, few are completely honest.
There is worry, like when a boat is in danger of crashing on the shore.

The subject

    
The bottom line (Earth-line) shows the change of the field or subject.
巽卦。 变初爻为乾, 风收云静, 廖廓一清。
风恬浪静.人物繁华, 风尘不动, 日月昭明, 星辰荣耀, 尊卑永荫, 始终太平。
Xun gua. The change of the bottom line activates Heaven. The wind silently drifts the clouds together, making the far-reaching sky pure and clean.
The wind is a light and agile breeze; man and matter thrive. The wind doesn't stir the dust; sun and moon shine bright; the stars sparkle.
There is no distinction between high and low. From beginning to end there is peace and harmony.

The outcome

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

  变中爻为艮, 风势入山. 动摇山岳. 令命上行, 人多敬畏。
When Xùn's middle line changes it activates Gěn. The wind penetrates the mountains and agitates their lofty heights; the destiny of life goes up, this person gets a lot of awe.

  

  The three 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. They reinforce the overall power of a reading.

  Advice or help for the initiative: Kan, Water, with his direction and focus, his courage to take risks and his talent to give things shape.
  Advice or help for the subject: Xun, Wind, with her power to choose and influence.
  Advice or help for the outcome: Gen, Mountain with his constancy, his ability to make things endure.
  But when things are not satisfying, it might be that one or more helpers don't help enough - or try too hard. Or maybe you don't listen carefully enough.
