The Celtic peoples of Britain emerged during an era veiled in antiquity, where oak groves, sacred wells, and flowing waters served as sanctuaries for Druidic ceremonies, worship, and ritual sacrifice. Their worldview encompassed a profound understanding that the past perpetually surrounds us, accompanied by a sophisticated and deeply felt sense of the sacred. Their imagination perceived nature and human existence as an integrated whole, refusing to distinguish between the visible and invisible realms, temporal and eternal dimensions, or human and divine spheres. The Celtic veneration of the soul's presence in all creation represents an unparalleled spiritual legacy in Western tradition. This indigenous spirituality underwent a transformation during the initial centuries of the Christian Era, finding expression in the symbolic fusion of the Christian cross encompassed by the Celtic circle of life.
