Little Sleep
“Mendicants, these five sleep little at night, staying mostly awake. What five? A woman longing for a man. A man longing for a woman. A thief longing for their loot. A king busy with his duties. A mendicant longing for freedom from the yoke. These five sleep little at night, staying mostly awake.”
