The stages of Community Building are:
Pseudocommunity
An initial state of "being nice". Pseudocommunity is characterized by politeness, conflict avoidance, and denial of individual differences. Let's be honest -- most of us can't keep this up for long. Eventually someone is going to speak up, speak out, and the dam breaks.
Chaos
In the stage of chaos, individual differences are aired, and the group tries to overcome them through misguided attempts to heal or to convert. Listening suffers, and emotions and frustration tend to run high. There are only two ways out of chaos: retreat into pseudocommunity (often through organization), or forward, through emptiness.
Emptiness
Emptiness refers to the process of recognizing and releasing the barriers (expectations, prejudices, the need to control) that hold us back from authentic communication with others, from being emotionally available to hear the voices of those around us. This is a period of going within, of searching ourselves and sharing our truths with the group. This process of "dying to the self" can make way for something remarkable to emerge.
Community
"In my defenselessness, my safety lies." In this stage, individuals accept others as they are, and are themselves accepted. Differences are no longer feared or ignored, but rather are celebrated. A deep sense of peace and joy characterizes the group.
