It is an individual responsibility to uncover its coherence, each according to their particular style, and to the extent of their ability. Each therefore creates and holds the coherence of the group it is not an external artefact, charter or rule to which individuals subscribe. There is no need to seek vainly to agree or to conform. This could not be a onetime process. Each is the instruments of other.
Individuals design each other in or out of their personal understanding of the quest.
There is subtle reinforcement and mutual entrainment. There is challenge. There is whatever one can individually dare to perceive and sustain. How people individually communicate with each other, and what they communicate, is a matter of personal choice. Such communications do not define the group.
