Here is the end of his "Song of Realization" by Chang:
Ye ghosts and demons, enemies of the Dharma,
I welcome you today!
It is my pleasure to receive you!
I pray you, stay; do not hasten to leave;
We will discourse and play together.
Although you would be gone, stay the night;
We will pit the Black against the White Dharma,
And see who plays the best.
Before you came, you vowed to afflict me.
Shame and disgrace would follow
If you returned with this vow unfulfilled.
Milarepa arose with confidence and rushed straight at the demons
in his cave. Frightened, they shrank back, rolling their eyes in despair
and trembling violently. Then, swirling together like'a whirlpool, they
all merged into one and vanished.
