In principle, each member attends to her/his own psyche and to the circle.
In the circle, as in life, the most valuable lessons often come through having done the best we could do with the most difficult circumstances. The circle and its members grow in depth through its hardest times. "That, which doesn't kill us, makes us strong."
The archetype of a circle may be perfect. A circle never is.
But if it holds its center when troubles arise and there is wisdom and compassion and honesty and room for making mistakes, the circle is more than "good enough." It is a creative work of art in process.
