She was founder of the Blue Cross and diaconical centre in Stará Turá. Her literary works were translated into 36 languages. During the reign of communist party in former Czechoslovakia, Christian literature written by her was among those frequently confiscated by state security service ŠtB and at the same time she was blacklisted on the socialist era school curricula. Nowadays she is considered to be the Slovak author with the most frequently translated literary works and some literary critics regard her for being a "Slovak Kierkegaard".
