Begging alms. A lot of people who are alone and cannot work, beg alms near places of worship. In Hinduism, the life of an ascet is one of the final phases, when one begins to look into the spiritual dimension after fulfilling one's duty in the material world. Begging alms has various connotation, both good and bad. I think of it as an exercise in releasing one's ego, thus being open to others.
