Always kind and considerate,” she continued. “In conversation she was able to penetrate into the deepest depths and also reach the highest heights of spiritual understanding. She upheld so many, seeing that their greatness was sometimes hidden from them, and always building bridges with her own connections to help them rise. She was everyone’s greatest champion. An inspiration for many.”
