The ability to influence

Chazal say Korach's wife pushed him into the rebellion against Moshe, and On ben Peles's wife kept him out of it. A Gemara in Sanhedrin and a Midrash on Moshe's words to Beis Yaakov point the same way. Why does a woman's influence reach so deep, and what is it about the heart that gets past the mind? The question reaches how we build a family, and why the Torah warns us not to follow our hearts. A recent wedding in Eretz Yisrael closes it, where a quiet influence showed itself.
