Rois is going back to school and needs a goddess of learning. She needs the Hindu goddess Sarasvati. Sarasvati invented Sanskrit, and she is remembered by Hindu students whenever it is test time. But, Rois, I think you will like her because of her flexibility.
She started out as a sacred river, and, you know, a river can tell you everything you need to know. It is ever changing, even the water is ever changing, yet, to the naked eye, it may seem more or less the same. That is Sarasvati's most important lesson: change is constant though often undetectable. If you can embrace that lesson, everything else will be a breeze.
PS: The photo is not Sarasvati. I used to use this thing called Zemanta for photos, but one day it just disappeared from my bookmarks and I can't figure out how to redo it. Thus, I am left to my own devices. I took this at the Getty Villa, which I love.
