The Bishnoi in India, the Aborigines in Australia, some American Indian tribes and some tribes in Africa give us hints of what it means to communicate with fellow beings on their level. Naturally future communities will re-find and apply such contents of archaic consciousness on a new level. The prevailing forms of global western civilization are based on colonial systems of conquest and on imperialism. Innately they are impressed by violence, lies, and fear, and so they don't have the ability for communication needed for their survival. Communities of the future therefore need a high level of self sufficiency in all areas of life to become independent of existing distributory and supply systems.
Self sufficiency is necessary in the areas of water, nutrition, energy, and medicine.
The answer can only be found from experience, but we will see that they cannot be too small. But communities of the future need to contain a high level of cultural, technological, spiritual, and biological variety to reach the complexity needed for a global cultural formation. When future communities are in resonance with the living body of the earth, they will have global impact. This is no pious hope but scientific law, because the living body of the earth is one unique organism together with the biosphere. If this organism gets a new information through the non-violent culture of a Healing Biotope, it will be effective in all of its organs.
