an.5.137 Aṅguttara Nikāya (Numbered Discourses)
Little Sleep
A man longing for a woman.“Mendicants, these five sleep little at night, staying mostly awake.
What five?
A woman longing for a man.
A thief longing for their loot.
A king busy with his duties.
A mendicant longing for freedom from attachment.
These five sleep little at night, staying mostly awake.”
