There are a few who in the practice of meditation climb so high that they can see from the top of the mountain. They are the mystics, to be found in all religions. The rest of us trudge along the foothills, knowing we may never glimpse the summit. And the journey is rarely easy. All who have walked the route to Compostela know how rough the terrain can be, and how on arrival at a hostel one sometimes finds the toilet rolls have run out or one is kept awake by the loud snores of fellow travellers! A pilgrimage makes demands. But we plod on!
