In today's Gospel reading from Mark 6, Jesus began sending the Twelve out two by two. He instructed them to take nothing for the journey but a walking stick ~ no food, no sack, no money in their belts. They were, however, to wear sandals but not a second tunic. It's clear that Jesus wanted the Apostles to live simply and put all trust in him. I can't imagine that he would advise us differently today. "Travel light" definitely applies to living the spiritual life, and it's made possible by full trust in God.
