Yi Jing, Oracle of the Moon

Kăn-Zhen, Water-Thunder
    

  When Kan enters Zhen, there is movement during danger. Often movement puts one out of danger, but neither Kan nor Zhen offer rest. You need a solid foundation and helpers to find your balance and security again. Since nothing is certain now, there are opportunities to explore new places and space for new seeds to germinate. Zhen opens up a new world of possibilities, and Kan puts in the hard work to exploit them. Together they cause the supreme freedom of tension, fears or rules.

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.
变初爻为兑, 水入泽中, 内塞不流, 终难远大,
  When the first line changes, Kan actives Dui. Water enters the Lake which it fills. Contained it cannot flow on; completion is difficult and takes long.

The outcome

    
The middle line (Man-line) shows the outcome.
  变中为坤, 水人地中, 防浸渗之乖・ 有壅塞不通之兆, 万事有始无终, 而无快变顺适之利。
   When the middle line changes Kan activates Kun. Water penetrates the earth which prevents it from seeping away. It is an omen of accumulation and obstruction; everything has a beginning but no end, there is no effortless and easy gain.

  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. Stationary helpers are part of the core meaning, they are your soul talking. They reinforce the overall power of a reading.
  Advice for the initiative: Xun, Wind, with her power to choose and influence, is lacking here or not needed. Yin remains Yin.
  Advice for the subject: Dui, Lake, with her ability to resonate and persuade, is lacking here or not needed. Yin remains Yin.
  Advice for the outcome: Kun, Earth, with her ability to nurture and concretize, is lacking here or not needed. Yang remains Yang.
  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.
