The Star represents hope, faith, and purpose. Inverted, it means distrust and disconnection. I chose Twilight for this because she has great faith in Celestia, as well as in her friends. She also has strong connections to others, her purpose lying as it does in bearing the Element of Magic and being the Princess of Friendship.
 
The bowls of water represent nourishment and refreshment, particularly of the mind. Twilight’s position, straddling land and lake, represents the need for balance between conscious knowledge and unconscious intuition, and the fact that she is bathing represents her vulnerability in this moment. The large star behind her represents her core essence, and the smaller stars floating around it are her connections to the world.
