Hexagram 12

Pĭ, To say no

Gua Poem: Say no to wrong people. The noble one's determination bears no fruit.  The great proceeds, the small comes up.

The great image says: Heaven and Earth do not interact: obstruction. The noble one holds back his virtue and avoids disaster. He does not allow honor by an official salary.

  Pĭ: the ideogram and the story. What does it mean for your question?
  This hexagram is complementary to hex.11.

Top 9: The obstruction is temporary. First obstruction, later rejoicing.
When an obstruction lasts for a while, one gets to know it, one realizes what it is, its why and how, and that announces its end. What one knows, one can handle and overcome. That also goes for interests which do not last: obviously they were not life giving, but obstructing. Even without being aware of it one lets them fade away.

9 at 5: Relaxed obstruction. Great people auspicious. One's extinction, one's extinction, fasten it to bushy mulberry-trees.
If you are obstructed and you feel frustrated or angry or sorry for yourself, your chances to get out pass by unnoticed. But if you are not tied to the difficulties but to grasping life the moment you can, to seize opportunities and hold them tight, then obstructions will never last long.

9 at 4: Having the mandate, no fault. Cultivate brilliance, happiness.
Giving orders is not a question of commanding people, it is in the first place inspiring them. A real leader is not the one in power, it is the one who brings safety, happiness and prosperity, the one who exerts a good influence all around, the one who is supported by the gods. To be that is a life-long duty.

6 at 3: Holding a sheep offering in expiation for a wrong.
Sometimes things stop through simple dumbness. No interest, no care, no love, no understanding. No way to get through that thick fog. The only solution is that the ones who make the fog also make it clear up. Don’t waste your time on them if they don’t.
(Changes to hex.33)

6 at 2: To work under contract. Small people: auspicious. Great people: obstruction for expansion.
When your situation among people is frustrating and you cannot use your wings and neither change it, then don't fret. Sometimes one simply has to adapt, so do it wholeheartedly. Happiness has more value than freedom. In this case those who have no ambitions are blessed.

Initial 6: Uproot Mao-grass, interlaced roots. Gather them together. Determination: auspicious. Expansion.
When life-energy stagnates and nothing interests you anymore, then start digging. The 10.000 things of the world may be outworn, but they have their roots in universal images. Search for the roots, they will inspire you again. Life needs weeding, then new things find room to grow.
