Your Week Ahead: The Himalayan caves are full of them. Renunciative hermits who dress in sackcloth, live on wild berries and spend thirty years at a time practising difficult yoga positions in total silence. Easy! A piece of cake! Beds of nails? No bother! Comfortable, by comparison to the beds that people like you and I end up making for ourselves and then become obliged to lie in. Nothing in this world is harder than to care about someone or something when the feeling hurts. But then, this week, nothing may prove more rewarding, either.
