sentences:  This distinction is significant, because rabbinic prohibitions may be set aside in cases where human dignity is undermined by a rabbinic norm.This principle of ""Gadol Kvod habriot shedocheh lo ta'aseh baTorah"" (so great is human dignity that it supersedes a prohibition of Torah) is found in Talmud Brakhot 19b and many other places in rabbinic literature and law.For example, Rabbi Eliezer Waldenberg used this principle to allow hearing-impaired Jews to use battery-operated hearing aids on Shabbat.
