“There is in Celtic mythology the notion of ‘thin places’ in the universe where the visible and the invisible world come into their closest proximity. To seek such places is the vocation of the wise and the good — and for those that find them, the clearest communication between the temporal and eternal. Mountains and rivers are particularly favored as thin places marking invariably as they do, the horizontal and perpendicular frontiers. But perhaps the ultimate of these thin places in the human condition are the experiences people are likely to have as they encounter suffering, joy, and mystery.” Peter Gomes
