Looking for the right symbol.

Seeking an image that captures what it feels like. Somewhere I've got a picture of a white tiger swimming that seems more like what I'm looking for - peaceful by nature, yet fierce when roused from her - slumber?

The swimming represents flexibility - an animal who *appears* to be most at home in the jungle, yet, when the need arises? Can do things others don't expect. Sort of an 'ace in the hole', or something.

Here she is:



























Isn't she GORGEOUS? :-)

Maybe I'll make my own Tarot and call it Tiger Tarot.

[Edited to add: Serenity seems like a possible name for this card.]
