" As Tam had taught him long ago, he formed a single flame in his mind and fed his fears into it, seeking emptiness, the stillness of the void. The flame seemed to grow until it enveloped everything, until it was too large to contain or imagine any longer. With that it was gone, leaving in its place a sense of peace. At its edges, emotions still flickered, fear and anger like black blotches, but the void held. Thought skimmed across its surface like pebbles across ice. "

― Robert Jordan , The Great Hunt (The Wheel of Time, #2)
