Yi Jing, Oracle of the Moon

Duì-Lí, Lake-Fire
    

    When Duì meets Lí, Lake's persuasion and Fire's clarity bring the compromises that make everything run in harmony. Conflicting intentions are exchanged and clarified and then the time is ripe for innovation and the work to realize it. Thus, the seasons follow one another, differing and also in agreement and mutually necessary.
  It is the ability to change with times or visions, to find, follow or create the transitions from one situation to another, and to compromise and balance instead of fighting and dividing.

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.
