Yi Jing, Oracle of the Moon

Gěn-Kan, Mountain-Water
    

  When Gěn changes to Kan, it is time to give up ambition and to follow your heart to find your way. Opinions close the entrance to your bliss. Start at the beginning, empty your mind and open it for the wisdom of those who went before. In order to find your way, it is not necessary to repeat every mistake ever made. Or listen carefully to the wind and to the earth, they tell the stories of life and death.

This is the short answer - click for the complete one.

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 mountain is strong but unmoving, Earth with her natural power of growth brings the chance of returning to life. She opens up Gěn's severity and shows which emotions are healthy and which are harmful, so Gěn can relax. A strong and also easy character is the way to success.
  General: yin initiative in yang potential will need perseverance. Everything around seems too bright, too overbearing. Don't try to compete, but make use of what presents itself to you. When the time is yang, it offers many opportunities and resources, brilliant ideas, but few concrete results. Yin's power is to absorb and then to create from what she gathered.
  You are a good organizer, you oversee the work and inspire others while working hard yourself. You can turn visionary ideas into viable plans.
  Yin at the top line brings the rain: blessings.

    The timing of this change of the initiative:
   春夏土膏肥厚, 生物荣华。盖山中地, 地中山, 正类谦尊而光, 卑而不可逾, 无往不利也。
  In spring and summer the earth is fertile and provides abundant food; all living things are glorious and resplendent. Thus: If the mountain is in the midst of the earth, or the earth in the midst of the mountain, then the upright man is humble and spreading light; modest and not overstepping boundaries, successful in everything attempted.

The subject

    
The bottom line (Earth-line) shows the change of the field or 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 (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.

  When the middle line of Mountain changes to yang, he activates Xun, the Wind. The mountain gets his inherently impressive image. Absorbing and processing his surroundings, he is an inspiring and giving leader. His influence will spread and he will earn respect and admiration. It is the power of a strong character, being true to oneself and to others. Able to overcome fear, greed and anything that keeps one from greatness. This is not an easy line and rules or past experience will not apply. It is a time of hidden danger. You will need willpower and persistence.
  General: When yin meets yang, it is time to follow up on your inspirations, to give a structure to visions or to share them. Performing the work turns into providing leadership. Others ask your advice or expect direction. The focus is on moving forward, showing results, enjoying what has been accomplished. You can energize and initiate, reconcile ideas and reality.
  The outcome changes from absorbing efforts or resources to giving back. You will need focus for what you do and the freedom to see chances and flow along with them. Use intuition and quick reactions; strict rules close off many opportunities.

The timing of this change of the outcome:
  春夏生蠹, 秋冬损物, 不如天风和时为美也。
   Spring and summer bring forth destructive things;
  Autumn and winter bring reduction of things.
  It is not as good as when the wind and time were in harmony.

  

  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.
