If I were you I would research all the characteristics of the white hart that you can find (where it lives, what its habits are, what it eats, etc.).
I would also research myths on the white hart as much as possible, and what aboriginal peoples believe about it.
Then I would focus on it visually as much as possible, place photos or figurines of it around your house, and then finally I would sleep on these discoveries for a few nights.
Then you will see how the white hart personifies you. It's strengths are your strengths, and its weaknesses are your weaknesses.
Then you will have a better idea WHY.
If you want to see journeys I have done and interpreted for others, you can look at my blog.
