Yi Jing, Oracle of the Moon

Kun-Kan, Earth-Water

  When Kun changes to Kan, Water imbues everything it encounters and applies its patterns to it. It makes sharp edges smooth, it enters the cracks in rocks and widens them, it makes the earth moist and undulating or soaked and unreliable. It lends its movement and patterns to the organs in living creatures. Water shapes everything in which it enters, for better or for worse.
  Kun builds and Kan shapes, Kun is battle, Kan is labor. They are the designers of life. Kun meeting Kan is about acting according to "the Way of Water".
  When Kun changes to Kan, Kun builds and Kan shapes, they are the designers of life. The result will be shining and giving joy, but the roots are showing, it is also a time of hidden danger. This is not an easy line and rules or past experience will not apply. You need your intuition, you will have to lead, give direction and flow with opportunities. In risky situations all depends on you.

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.
