The Bible speaks of various postures in prayer (standing, kneeling etc.).
We have just had a few days holiday in Spain. At the departure gate, a group of maybe ten young men from south London formed a prayer huddle - an inward facing circle, arms around one another.
Good for them, I thought. I'm not sure it would be quite my cup of tea, but it seemed to express a resolve and solidarity: the boys on tour contra mundum.
