"Thudong monks valued wandering as an ascetic practice, as a means of training the mind to face hardship and the unpredictable. Whenever they wandered far from the relative comfort and security of the monastic life, they had to contend with fear, pain, fatigue, hunger, frustration, and distress; and sometimes they risked death. ... [A monk] never knew where he would spend the night, where the next meal would come from, or what difficulties he would encounter. He learned to live with insecurities and discomforts - life's inevitable dukkha."
