These are the elements present as part of the process for most Jewish weddings:
1. an ufruf, where the impending marriage is blessed up at the Torah during a Shabbat prior to the wedding. During their aliyah often the couple is pelted with candy, suggesting a blessing for a "sweet relationship".
2. the day before or morning of the wedding, a private immersion ritual readying of body and soul called mikveh,
Behind this list of terms is a world of spiritual beauty which it is helpful to study in order to be fully able to appreciate the power and mystery of the Jewish wedding. There are many magnificent ritual, liturgical and mystical options and elaborations for wedding preparation, as well as for the wedding itself.
