This morning I received a text message that a member of my extended family will likely die of cancer within the next few hours. His name is Luke. He is a 45-yearold husband and father of six. Though I am not as close to him as my sister (she is his sister-in-law and knows him well), I wonder: how can we, including Luke himself, manage such a terribly awful and unfair situation?

One of the most touching YouTube videos I’ve ever seen is one in which a deaf woman receives new technology to heal her hearing. She hears her husband's voice for the first time — and her own, too — and bursts into tears of overwhelming joy. It must have been like an immovable wall between her and her loved ones came tumbling down.

Purity isn’t popular at the moment. Or is it? Look at a rack of health magazines or at popular podcasts. You’ll see an infinite ocean of regulations and rituals of diets, intermittent fasting, morning sun rituals, intense juice detox practices, lists of dangerous foods, mental practices, as well as long lists of dos and don’ts for the proper cleaning of clothes, dishes, cars, houses, pets, and children. Like it or not, we long to be pure, clean, and without blemish.
