Yi Jing, Oracle of the Moon

 Kăn-Gèn, Water-Mountain

    

  When Kan enters the mountains, Gèn directs the water, it provides the boulders and crevices to either prevent it from finding solutions or to accelerate it on its way. There is no telling where it will end up, but that also gives the freedom, or compels the necessity, to find new solutions and follow any road that opens up.
  Kan with Gen is like a water canyon. Danger and risk, but if you embark on it, it also gives the elation of finding an unexpected new path and the thrill of having dared to tread it.

  Initiative yin-yang: find new ideas, use your brain and influence.
  Outcome yang-yin: be realistic and work hard.

This is the short answer - click for the complete one (with 'your' helpers).

  About the 3 lines of the trigrams and the 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 or what is lacking at the moment. They reinforce the overall power of a reading.
