Yi Jing, Oracle of the Moon

Gěn-Gěn, Mountain-Mountain
    

  What are the potential and qualities of this situation?

Gěn or Mountain. He is high but does not boast, is strong but does not force anyone. Gen may be grumpy or a recluse but has a good heart and cares. Gěn is about individuality, staying true to yourself even when it is difficult and giving in would be easier. Gěn stands high above the valley below and seems aloof, but the mountain shelters and feeds the valley, makes the clouds release their water and sends it down to the vegetation and all creatures at its foot.

  What do you want or need to do, or what will fate cause to happen in this situation?
  Gěn-Gěn is not the same as Gen unchanging. It is mountain after mountain, a mountain-range. It can be a succession of concrete accomplishments, or a long time of big challenges and problems or simply a solidifying of everything as it is.
  It is also the way you are who you are, day in day out, true to yourself and dependable for others.

The initiative

   The top line is stationary yang. A yang initiative, entering a yang world, fits right in. Both clear and inspiring, full of plans. Even when other things change, you will remain giving, pouring ideas, efforts or money into this situation. Yang brings and spreads creativity and ideas with a good basic structure, It is the master of good timing and planning, but not of finding a final solution or concrete results.
  Stay within limits, Yang is also prone to deplete itself. It is relentless, and it can focus so intensely on mental images that they can turn into air castles or delusions. Yin is necessary for concrete results but not before the planning is right, too early can be disastrous, no matter the quality of your ideas or how determined you are.

Yang has the talent to enjoy the road
before reaching any destination.

The subject

  The Earth-line is unchanging yin. This line is the subject, or the ‘field’ where you pour in or find both the cause and the means for your initiative: space, material, helpers or other people, resources and realization, even food for thought. It is a 'receiving' line, the earth needs input and resources to make things grow and bring concrete results.
  Your subject or project will stay attractive, but it will continue to absorb and process and use it to continue the work. It will not shine on its own or show increase to the outside, the work of building up happens in the background.

Beauty comes from the space within.

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.

Overview of the lines.
Activating (when the second is different) or stationary (when they are similar)

  A Yang line is generally bright and giving. Yang is great for enthusiasm and spreading joy or success, but don’t expect solid results.
  A Yin line generally does the work. Yin absorbs and converts resources into tangible results. It brings peace and a sense of security.

  The initiative (top line or Heaven line) is the intention or focus. Your ideas, plans, or what you want, or something that happens and you want to influence it or use its possibilities.
   In this answer the line is stationary Yang: the initiative is clear and strong, this is a good time to develop visions and plans, pouring in creativity, efforts and enthusiasm.

  The subject (bottom line or Earth line) is the 'reality' of your question or the ‘field’ of action. A situation or person, resources, materials, facts.
   In this answer the line is stationary Yin: it is too early for clear results; more work is needed. This line is the most difficult to influence, she is careful and follows her own creativity and decisions, but she is the one who turns resources into concrete results.

  The outcome (middle line or Man Line) is what you or others or fate cause to happen 'between Heaven and Earth'. It is the outcome of this question. It can be physical or mental or both. If this is a yes/no question, then yang means yes, yin means no. Both can be good or bad, depending on the question.
   In this answer the line is stationary Yin: Yin: A good line for concrete results. More work is needed, but your dedication is not in vain. For now, it will reduce the 'shine' because it focuses on creating, on growing something of quality, not on the result itself.

  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: Kun, Earth, with her ability to nurture and concretize, is lacking here or not needed. Yang remains Yang.
  Advice for the subject: Li, Fire, with her power to discern and create order, is lacking here or not needed. Yang remains Yang.
  Advice for the outcome: Xun, Wind, with her power to choose and influence, is lacking here or not needed. Yin remains Yin.
  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.

  This oracle is NOT according to the Neigua Chuwaili, a chapter of the Heluo Lishu, which is meant to be read and used in Chinese astrology. But I found beautiful texts about the trigrams in the Neigua Chuwaili and borrowed them for this trigram oracle. For those who are interested in the Heluo Lishu see the course by Harmen Mesker.
  Many translations from "Yijing astrologie" by Harmen Mesker (Dutch).
