Many Hindu deities are depicted with several arms.

"Such multiple body parts represent the divine omnipresence and immanence (ability to be in many places at once and simultaneously exist in all places at once), and thereby the ability to influence many things at once." (Wikipedia on Hindu iconography)

Robin confirmed for Hindu goddess!

In fact, I'm surprised there aren't more images of her in reminiscence of Hindu icons.

EDIT: Wait, is that the reason Oda changed her hair?!
