It is this consistent reminder that erases Amalek from the face of the earth. This discussion is quite puzzling. The B'nai Yisrael sense a contradiction between the requirement to remember the deeds of Amalek and the obligation to sanctify the Shabbos. The Maharal explains Havdala as the process of distinguishing between Kodesh and Chol, understanding the difference between the secular pursuits of a material world and the sanctity of a higher realm. While a man provides the initial core of individual rejuvenation and rebirth, a woman is the one who organizes and arranges the proper order of life.
Man makes distinctions, while women put things in place.
The Zachor remembers. He who makes Havdala properly, will have a son. In a world that tries to make us forget, we have no choice but to make Havdala, separating the good from evil, Shabbos from the workday week, and this world from the next. Klal Yisrael perceives this world as a temporary station, a transit stop on the road to an eternal destination. The world has a beginning, an origin of meaning and direction, and it exists as a process, developing towards a meaningful end.
