SN4.12 — The Lion's Roar Discourse

At one time, the Blessed One was dwelling at Sāvatthī in Jeta's Grove, Anāthapiṇḍika's Park.

At that time, the Blessed One was surrounded by a large assembly, teaching the Dhamma.

Then it occurred to Māra the Evil One, This ascetic Gotama is surrounded by a large assembly, teaching the Dhamma. Let me approach the ascetic Gotama to create confusion.

Then Māra the Evil One approached the Blessed One and addressed him in verse:

Why do you roar like a lion,

Confident in the assembly?

Do you have a rival,

Do you think you are victorious?

The great heroes do roar,

Confident in the assemblies;

The Tathāgatas have attained strength,

Having crossed over the world's attachment.

Then Māra the Evil One, realizing The Blessed One knows me, the Well-Gone One knows me, sorrowful and dejected, vanished right there.
