NY Times: A German Voyager’s Bold Vision for Tibet’s Blind. (No registration required; this is a mirror on Heidi Connal‘s site.)

I recently read her book My Path Leads to Tibet: The Inspiring Story of How One Young Blind Woman Brought Hope to the Blind Children of Tibet (deutscher Titel: Mein Weg führt nach Tibet – die blinden Kinder von Lhasa).
