Yevamos 101a: Is Chalitzah A Mitzvah?

Is chalitzah simply the procedure that releases a yevamah to remarry, or is performing chalitzah itself a mitzvah? And if it is a mitzvah, what happens when the woman refuses? Can Beis Din force her to participate in chalitzah even if she has no interest in remarrying? We explore the nature of the mitzvah of chalitzah and the fascinating question of whether a person can be compelled to perform it.
