The Discourse on Ascetic Practice
137.
Thus have I heard -
On one occasion the Blessed One was dwelling at Uruvelā on the bank of the river Nerañjarā at the root of the goatherd's banyan tree, newly fully enlightened.
Then, when the Blessed One had gone to a private place and was in seclusion, this reflection arose in his mind:
"Indeed I am released from that performance of austerities.
Good! Indeed I am released from that unbeneficial performance of austerities.
Good! Indeed I am released and have attained enlightenment."
Then Māra the Evil One, having known with his mind the reflection in the mind of the Blessed One, approached the Blessed One; having approached, he addressed the Blessed One in verse -
Being impure you think yourself pure, you have failed from the path of purification."
Then the Blessed One, having understood "this is Māra the Evil One", addressed Māra the Evil One in verses -
All is not bringing benefit, like an oar on dry land.
I have attained the supreme purity, you are defeated, O Death."
Then Māra the Evil One, thinking "the Blessed One knows me, the Fortunate One knows me", afflicted and unhappy, disappeared right there.
