Asha had no claims. Her husband was an alcoholic, an itinerant construction worker, a man thoroughgoing only in his lack of ambition. As she’d raised their three children, who were now teenagers, few neighbors thought of her as anyone’s wife. She was simply Asha, a woman on her own. Had the situation been otherwise, she might not have come to know her own brain.
It wasn't what she had - it was what she didn't have or avoided that allowed her to "discover her own brain."
