The Discourse on Sleeping
143.
On one occasion the Blessed One was dwelling at Rājagaha in the Bamboo Grove, the Squirrels' Feeding Ground.
Then the Blessed One, having walked up and down in the open air for much of the night, towards the break of dawn, having washed his feet, entered the dwelling and lay down in the lion's posture on his right side, overlapping foot upon foot, mindful and fully aware, having attended to the perception of rising.
Then Māra the Evil One approached the Blessed One;
having approached, he addressed the Blessed One in verse -
Why do you sleep like an unfortunate one?
Thinking 'My house is empty' you sleep,
Why do you sleep when the sun has risen?"
That craving to lead anywhere, does not exist;
The Buddha, with the utter elimination of all clinging,
Sleeps - what is that to you, Māra?"
Then Māra the Evil One, etc. disappeared right there.
