In every cluster, once a consistent pattern of action is in place, attention needs to be given to extending it more broadly through a network of co-workers and acquaintances, while energies are, at the same time, focused on smaller pockets of the population, each of which should become a centre of intense activity. In an urban cluster, such a centre of activity might best be defined by the boundaries of a neighbourhood; in a cluster that is primarily rural in character, a small village would offer a suitable social space for this purpose. Those who serve in these settings, both local inhabitants and visiting teachers, would rightly view their work in terms of community building. To assign to their teaching efforts such labels as "door-to-door", even though the first contact may involve calling upon the residents of a home without prior notice, would not do justice to a process that seeks to raise capacity within a population to take charge of its own spiritual, social and intellectual development. The activities that drive this process, and in which newly found friends are invited to engage--meetings that strengthen the devotional character of the community; classes that nurture the tender hearts and minds of children; groups that channel the surging energies of junior youth; circles of study, open to all, that enable people of varied backgrounds to advance on equal footing and explore the application of the teachings to their individual and collective lives--may well need to be maintained with assistance from outside the local population for a time. It is to be expected, however, that the multiplication of these core activities would soon be sustained by human resources indigenous to the neighbourhood or village itself by men and women eager to improve material and spiritual conditions in their surroundings. A rhythm of community life should gradually emerge, then, commensurate with the capacity of an expanding nucleus of individuals committed to Bahá’u’lláh's vision of a new World Order.
