A ritual pool or gathering of waters used for ritual immersion to mark a significant life cycle moment, celebration, or transition, or as a component of the conversion ritual. In some Jewish communities, married women immerse each month at the conclusion of their menstrual cycle. Customarily, a bride immerses in a mikvah prior to her wedding and today, both brides and grooms might immerse prior to their wedding. Some people immerse to prepare for Shabbat or holidays. There are many creative rituals for using the mikvah at any significant lifecycle moment. Immersion in a mikvah is also a final step in the conversion process; a natural body of water also can serve as a mikvah. Plural: mikvaot.
