What are the principles (rules) of the game? 

The Principle of Community — The Seeds will be found in relational experiences.

• Seeds only exist in “community”. Because they are not “things”  but living “propagators” they only exist in living systems, i.e relational fields;

• these fields encompass, biological, intimate, social, intrapersonal, transpersonal relations;

• the particular relationship in which a seed is discovered, is the optimum “soil” in which it may be planted.

 
The Principle of Sincerity — Seeds will only disclose themselves when you are being sincere.

• “Sincerity” here means, being true, transparent, available without judgements or equivocations;

• the fruit of these Seeds are only useful to the true self, the one behind the various roles we have played and play and the stories we have told and tell about ourselves;

• the cultivation of Seeds for limited purposes (I want to be rich, for example) may only yield unhelpful disruptions, and might even impede future gardening.

 
The Principle of Commitment — The potency of a Seed you find will be proportional to the commitment you make to its cultivation.

• “Commitment”, in this context, could be defined as the steadiness with which intention, will, and love are aligned with the power of the Seed; 

• and the consistency with which that steadiness is refreshed and deepend throughout the entire discovery-cultivation-harvest process;

• it’s also a function of how willing and able we are to fully integrate the seed’s fruition—new modalities of perception, thought and action. 

 

The Principle of Uncertainty — Seeds are found in the Imaginal—a liminal space where everything both is and isn't what it seems.

• We might think that uncertainty would make it impossible to act in a definitive way, but in The Seed Game focused direction is balanced by holy doubt; 

• The more we believe we can define anything, the further we drift from its truth.

• The underlying message of The Cloud of Unknowing suggests that the way to know God is to abandon objective consideration of God's particular activities and attributes, and be courageous enough to surrender one's mind and ego to the realm of "unknowing" (the Imaginal) to glimpse the nature of God.

The Principle of Magical Realism — Seeds are found when the “imagined” is made real.

• “Reality, including this very moment for you and me and the whole Enormous Show everywhere, is inventing itself as it goes. It is alive and creative and free. Of course, each of those words, “alive,” “creative,” “free,” can get stuck in our objectifying minds as things we think we know, but we have the intuitive capacity to let them loose, to sense them beyond their word-forms in the undefined, spontaneously creative openness that we share with Godness itself.” - Pir Elias Amidon, from “God is Not Something Already Made”
