Without getting too heavy and because you asked:
I see the image of the man as "self" and the light in the background as his desired destination - awareness, skill, success, etc.
The self stands in the darkness and seeks to move into the light. The wolf represents all the personal inhabitions and mental/physical obstacles placed on self by self - a formidable adversary. Once the wolf is defeated the goals are attainable; however there are still mountains to climb in the distance and although the journey is easier once the wolf is defeated - defeating him is but the first step to move closer to the light.
The stick could represent the desperation of self to defeat the wolf. It is the logical weapon of choice since nothing else is available (ignorance, the usual tactics, the known quantity) and the first attempt to gain an advantage on the wolf (the "easy" road - what we're accustomed to doing when a challenge arises)....but what will eventually defeat the wolf is intellect and gile, agility and application of training (especially if you've watched the movie).
That's what is says to me anyway.
