"Remember what Amalek did to you when you went out of Egypt!" are the words of caution we read in the Torah on this Shabbat before Purim.
Amalek was the nation who attacked us when we left Egypt. Although they had no direct quarrel with the Israelites, they still attacked us, with the sole intent of "cooling down" our trust in G-d and our enthusiasm for entering the Promised Land.
Today, our task to remember Amalek is a spiritual one. It is to be constantly aware of one the greatest dangers facing each of us, personally and collectively: The danger of doubt that curbs our enthusiasm and leads to coldness, indifference and apathy; a coldness that stunts our efforts of pursuing spiritual growth and continual self-improvement.
