Yi Jing, Oracle of the Moon

Zhèn-Kan, Thunder-Water

    

  Zhèn meets Kan. The development of seeds is often held back by cold or fear, but Kan shelters the seeds and Zhèn makes them germinate. When Thunder shakes the water up, it evaporates into mist, clouds and rain. Every spring and in every new start, Thunder and Water together create a new cycle of life. Without them there will be successions but very few new creations.
  When Zhèn meets Kăn, Thunder has access to the formlessness and dare of Water. Then Zhèn moves without any restriction.

The initiative

    
The top line (Heaven-line) shows the change of the focus or initiative.

  The top line is generally where the initiative comes from, but here it is yin, both in- and outside. It might be that you asked about a matter where the initiative or action doesn’t come from you. Yin is compliant and absorbing and occasionally accepts too easily, but it keeps the excess of dominance and lack of empathy of the Heaven-line in balance. A yin Heaven-line may bring rain: blessings – concrete sustainable solutions.
  Yin will reinforce you to process ideas and projects and to continue working on them. Yin is not aiming for success but for a job well done. It is nurturing and attractive, but there will be no output yet, for the time being your plans ask input, like ideas, energy, maybe money, and keep doing so for the time being.

When plans include the work, they will thrive.

The subject

    
The bottom line (Earth-line) shows the change of the field or subject.
变下为坤, 为地, 雷人地中, 雨泽不施也, 必致饥荒。
主人无识, 萧索乖戾, 中生多阻。
  The bottom (line) activates Kūn, activates earth. Shocks in the earth, no rain will fall in the marsh, it will lead to a poor harvest. There is no hesitation; the determination is reckless. 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.
变中爻为兑,为泽,雷泽交施,
When the middle line changes, it activates Dui, which activates rain. Thunder and rain work together.
  (施 is harmonious cooperation: image of a flag, "following the wind")

  

  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: Li, Fire, with her power to discern and create order, is lacking here or not needed. Yin remains Yin.
  Advice or help for the subject: Kun, Earth, with her ability to nurture and concretize.
  Advice or help for the outcome: Dui, Lake, with her ability to resonate and persuade.
