Yi Jing, Oracle of the Moon

Lí-Lí, Fire-Fire
    

离卦。离为火, 为日, 吐焰发耀, 光照天下, 太阳之三三 象，
长育之君, 万象贤明, 百物附丽。
 Neigua: Trigram Lí is fire, the sun, spewing flames and brightly radiant; its rays illuminate everything under the sky, its image is again and again eminent yang.
  It is the lord of lasting development. The source of life and clarity for everything on Earth, all beings bind themselves to it.
Lasting development (Chángyù): like cattle breeding or plant cultivation. Li, separating, fences: your own field.

  What are the potential and qualities of this situation?Lí. It is the trigram of discernment and order, of searching for truth and meaning. Lí is separating or leaving, but also clinging, holding on to things. It is what light does: discerning things, seeing their differences and similarities. Both by recognizing and acknowledging them.
  Fire can easily be extinguished, buried under earth or water. To spread light and warmth it needs to be nourished itself. Attention, inspiration, order and truth will make it shine wide and spread its warmth, like the sun emerging from the clouds.
  Moments fly past like birds. You will have to catch them right now, to enjoy something when it happens, to seize an opportunity, to realize a flash of insight.
  But reckon with its timing, don't try to push two days into the space of one or it will burn you to ashes.

  Lílí means luxuriant or 'not attend personally'. Fire follows guiding stars, it looks beyond its own presence to the grand whole. Repeating Li is also the succession of days, of the sun which rises again every morning. It can be hidden by clouds but nothing can make it deviate from its course. It is the strenth of character which follows what has to be done in any circumstances without reckoning with personal advantage. But reckon with its timing, don't try to push two days into the space of one or it will burn you to ashes.
  It is also the ability to make a show when necessary, to make others see what one wants them to see.

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 bottom line is stationary yang. 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, even food for thought. It is the line of the earth, of resources and realization. It is a 'receiving' line, the earth needs food to develop things.
  Here she is yang, she does not absorb or concretize, she is giving. Things look interesting and bright and give back. What you want to achieve inspires you, but take care not to deplete resources. Things will gain clarity but it is not yet a time of concrete results.
  Yang at the bottom line brings balance between yin and yang. Its light penetrates the undefined power of the earth-line, it inspires yin to make its imaginings grow, and it gives each creature or plan or venture its rightful structure.

Enjoy the now and its possibilities.

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)

  An activated Yang line is generally bright and giving.Yang is great for enthusiasm and spreading joy or success, but don’t expect solid results.
  An activated 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 Yang: the subject is clear and generous and responds to the initiative. Usually yang at the bottom is positive, there is balance between yang and yin.

  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: a good line if you need decrease or concreteness, but not for shining results. More work is needed, but your dedication will not be wasted.

  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: Zhen, Thunder with his energy and stimulation and quick actions
  Advice or help for the subject: Gen, Mountain with his constancy, his ability to make things endure
  Advice or help for the outcome: Qian, Heaven, with his severe structure and his timing, 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. 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.
