I guess my question is:
Upon what do you wish to reflect on:
your navel, an inner being, the meaning of life, the meaning of death and what follows, there are a myriad of topics.
Might I suggest you consider this:
Find a VERY quiet place away from the crowds...close your eyes and breathe. What do you hear and what does it signify. Do you hear birds, crickets, cars off in the distance, or a jet flying overhead? What does that mean to you, to the world, to the Camino.
Find a fairly noisy spot: Seek out a sound different from the normal press of sounds: a baby crying in the distance, a train whistle, bells on a cart. Why did that particular sound appeal to you among all the others. Could it be you have a new baby in the family you miss, did you arrive for you Camino by train and it's calling to you...helping you along, do the bells...as small as they are still ring true amid the clatter and the great bells of the cathedral?
Why...seek out! Well, to be practical...you don't have to carry the extra weight of a book. You only have to engage your mind!
Press on!
