Yi Jing, Oracle of the Moon

Xùn-Kăn, Wind/Wood-Water
    

  When Wind activates Water they form a force that man cannot change. Both trigrams have a relentless movement, both extremely strong and devastating - and extremely gentle and caressing. Together they work from tiny creative beginnings all the way to huge disasters.
  Feng-shui, wind-water, is the art of shaping the environment and landscape but also reading it: geomancy. It is how the emperor rules the people: reading the patterns and giving them patterns to follow. Knowing the patterns of your life will allow you to acknowledge or dissolve them and reshape your way. When patterns change or dissolve, opportunities will appear, sudden moments that are not yet defined. A quick mind can seize them, but be careful!
  The great image says: "Winds blowing over the waters: flood. The ancient kings presented offerings to the Lord and established temples". Even kings need assistance in times like this.

  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.
