Due to her experiences as a Holocaust survivor, she became "determined to devote her life to combating the spiritual holocaust that was occurring here in the United States." This led to the birth of the Hineni movement on November 18, 1973, in Madison Square Garden's Felt Forum. The movement aimed to promote authentic, traditional Yiddishkeit in the United States. As the leader of this movement, she drew criticism for her outspoken stance against interfaith marriages. She was also critical of secularization, which she viewed as a form of assimilation.
