Yi Jing, Oracle of the Moon

Gěn-Zhèn, Mountain-Shock
    

  When Gěn changes to Zhèn, the solid Mountain gains new life. Sometimes in small ways, hardly visible, sometimes big. Maybe a shower awakens the seeds on its flanks. Maybe a fire destroys the old trees and new vegetation comes up. Maybe a rigid mind lets go and there is a change in expression. Maybe an old habit is discarded for the sake of new discoveries. Life on earth needs disruptions or it will become stale and old. They bring the food for renewal.

This is the short answer - click for the complete one.

The initiative

    
The top line (Heaven-line) shows the change of the focus or initiative.
变上为坤, 舍崇高而从卑下, 脱崎岖而履平坦, 土命逢之, 温厚和平, 成始成终。
When the top line changes it activates Kun. Following from a high place to a low place; leave the rough terrain and follow the level path. Whoever has an affinity to Earth will find it and be successful from beginning to end.
(affinity to earth: Tu Ming, earth name/destiny, born in an earth year or having a local or popular name - a lasting link to Earth.)

The subject

    
The bottom line (Earth-line) shows the change of the field or subject.
变下为离, 日出于山巅为朝, 为旦, 主人升上三三近贵, 洞晓明彳散, 高下瞻仰, 福禄兼备。
When the lower line changes it activates Li. It is the sun rising over the mountain top; it is the morning, the dawn. This person is climbing to an influential position and has a clear insight; high and low behold him with high regard. Happiness and wealth will be his.

The outcome

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

  The middle line indicates the result. It is unchanging yin, this project will stay attractive, but also continue to absorb efforts, knowledge or resources, because its developing stage is not finished and not all possibilities have been explored. It still needs input and keeps doing so for the time being. It is too early to decide about a final direction, there will be no output yet.
  But yin is the one who can bring about concrete results. Yin stays in the background and does the work. It is nurturing, defusing crises, monitoring the process, building up and rounding out.
  This is the 'man' line, it can also be about you yourself, not only what you do.

Love for the work dissolves the effort.

  

  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: Kun, Earth, with her ability to nurture and concretize.
  Advice or help for the subject: Li, Fire, with her power to discern and create order
  Advice or help for the outcome: Xun, Wind, with her power to choose and influence.
  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.
