After exploring marriage and love in the first two parts of this series, a critical question remains: How can a couple ensure that their marriage will remain strong, vibrant and special throughout their lifetime? We already addressed three essential aspects which will help spouses establish a solid marriage: (1) continually acting as an ezer knegdo (soul mate) to help their spouse reach their potential, (2) recognizing that the essence of love – ahava – is based on genuine concern, giving – hav – and hard work, and (3) strengthening, sharing and drawing nourishment from strong Jewish values in building a Jewish home together. In this class, we introduce a fourth component – the powerful glue of the couple that is created by the mitzvot of Taharat HaMishpachah (family purity) and the mikvah (ritual bath).
