Kill the Sha of Doubt.
There is an ancient pandaren saying that states, "With deep doubts comes deep wisdom."
The Sha of Doubt has infested the Heart of Jade within the temple. It must be destroyed.

Return to me when you've completed this challenge, and I shall reward you handsomely.
I never doubted you. Funny though, you don't look any wiser.
<The master winks.>
