Yi Jing, Oracle of the Moon

Gěn-Duì, Mountain-Lake

    

  When Gěn changes to Duì, the individual encounters the deep sense of connection with friends or family or, on a larger scale, humanity. This sense of belonging brings rest to the soul. But it also brings frustration and the feeling of being a victim of another or of larger powers.
  There is the openness that connects with the spirits and intrigues others, apparent as the skill of reaching out. But there is also the individual who is true to his own values and has to protect himself against the demands of society and the ruthlesness and greed of a large part of humanity.
  When exchange with others and staying true to yourself can both give in to reality and respect the needs of each other, they will find the right balance.

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.
  变中爻为巽, 风生岩谷, 山虚石出, 居高多险, 任重多危・
When the middle line changes it activates Xùn. The wind blows over the rocks and valleys. From mountain hollows rocks tumble out. High residence has many risks, those who hold important positions experience many imminent dangers.

  

  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.
