Then Mara the Evil One, wanting to arouse fear, horripilation, & terror in her, wanting to make her fall from solitude, approached her & said, "Whose philosophy do you approve of, nun?"

"I don't approve of anyone's philosophy, my friend."

[Mara:]

For whose sake
    have you shaved your head?
You look like a contemplative
but don't approve of a philosophy,
so why are you wandering here
    confused?

[Sister Sisupacala:]

Outside philosophers place
their confidence in views.
I don't approve
    of their teaching.
They're not adept
    in the Dhamma.
    But there is
the Awakened One,
born in the Sakyan clan,
a person without peer:
    all-conquering,
    Mara's subduer,
everywhere undefeated,
everywhere freed, independent;
        endowed with an Eye
    all-seeing, reaching the end of
    all kamma --
with the ending of acquisitions,
    released.
He, that Blessed One,
    is my teacher.
It's in his Dhamma
    that I delight.

Then Mara the Evil One -- sad & dejected at realizing, "Sisupacala the nun knows me" -- vanished right there.
