Nicely written, and so very topical. Also worth comparing the cultural differences between the East and the West when it comes to the notion of cleanliness.. I once read something very interesting about what Swami Vivekananda had to say about it.. something to the tune of .. Indians may wear unwashed clothes .. but they take a bath everyday .. in the west it is the other way round .. both have something to learn from the other. and the implicit metaphor about cleanliness of the body and the mind/soul.
