Yi Jing, Oracle of the Moon

Duì-Gěn, Lake-Mountain
    

  When Dui activates Gěn, relationships with people gain trust because Gen, the mountain, is an individual, true to himself, without any artificial way of presenting himself. It is a prerequisite for real connections to know someone and without an understanding of the person you are dealing with - and especially an understanding of yourself - an open relationship is not possible. But when Duì connects two individuals, they can form a whole. It is the foundation of a life in which they support and complement each other. Together they can tackle things that are difficult for one person alone. A single mountain isn't enough for a rich natural environment; it is the mountain range, creating and sustaining its own climate, that supports the diversity of life.

  About the 3 lines of the trigrams and the spirit 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.
