Yi Jing, Oracle of the Moon

Kūn-Lí, Earth-Fire
    

  When Kun activates Li, the sun descends into the earth, it becomes dark. But Fire and Earth also mutually support each other, their relationship is harmonious, and the darkness will not last. Great difficulties will bring happiness if one can cope with this succession of dark and light, if one knows how to use both darkness and brightness, each in its own time.
Use your intuition, it tells you when to show yourself, your intentions or actions, and when to hide all that. If you doubt, then lean to the careful side. Showing can have dire consequences, hiding is usually safer. Just don't make it your standard reaction, stay flexible.

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.
