Katara - One of my favorite story lines. She was more herself as the Painted Lady then I think she was given an opportunity to be during the rest of the series. Here she could help. There was no one who could stop her from helping people. No one expected her to be someone she wasn't.
Why would anyone want to embark on the daunting inner journey...because there is no way out of one's inner life, so one had better get into it. On the inward and downward spiritual journey, the only way out is through. Parker Palmer
