The word "humility" (also "human") is derived from the Latin "humus," meaning "the soil." Perhaps this is not simply because it entails stooping and returning to earthly origins, but also because, as we are rooted in this earth of everyday life, we find in it all the vitality and fertility unnoticed by people who mostly tramp on across the surface, drawn by distant landscapes.
The very thoughts that allow us to hurt another limit our ability to express the will of creation through ourselves. At the same time, each time we love another, we have just loved ourselves. Each time we create time for another, strive to understand another, we have just done each of these things for ourselves. When we disapprove of the actions, choices or beliefs of others, we witness through them those portions of ourselves that ask for a greater healing.
