"A group of individuals coalescing around a powerful calling question. Many of these conversations are taking place in cyberspace, among groups that are networked across the globe. Many individuals are active in several networks, thus functioning as nodal connectors, cross-fertilising the multiple conversations in which they are engaged. Occasionally, individual members of these dispersed networks manage to make it into the same physical space, for retreats, conferences… any excuse. They have great parties and the time they spend together tends to be transformative, turboing the individuals to ever greater depths of wisdom and heights of consciousness. Bonds are strengthened and the quality of the inquiries and conversations is powerfully augmented."
