We Have The Power
....Haman, a direct descendant of Amalek, was driven by similar hatred of the Jews, because "their laws were different from those of any other people," as the Megillah states. Likewise all subsequent Amalakites and Hamans of all ages.
But "Amalek" - in a wider sense - represents all obstacles and hindrances which a Jew encounters on his, or her, way to receive and observe the Torah and Mitzvos with enthusiasm and joy in the everyday life. And so Parshas Zachor comes to remind us, and never forget, that "Amalekites" exist in every generation and in every day and age, and that we must not allow ourselves to be deterred or discouraged by any Amalekite in any shape or form.
If the question be asked, "Why has G-d done thus?" Why should a Jew be confronted with such trials and difficulties? - the answer is that every Jew has been given the necessary powers to overcome all such "Amalekites," and he is expected to use them, in order to demonstrate to himself and others that nothing will deter him, nor dampen his fervor, in the observance of the Torah and Mitzvos in accordance with G-d's Will. And once he recognizes that whatever difficulty he encounters is really a test of his faith in G-d, and resolves firmly to meet the challenge, he will soon see that no "Amalek" of any kind is a match for the Divine powers of the Jewish soul. Indeed, far from being insurmountable obstructions, they turn out to be helpers and catalysts for ever greater achievements, having been instrumental in mobilizing those inner powers which would have otherwise remained dormant.
This is also forcefully brought out in the Megillah, in the example of Mordechai the Jew, who "would not bend his knee nor bow down" before Haman. As a result of this indomitable stance, not only was Haman's power totally broken, but many enemies became friends, as the Megillah tells us that "many of the peoples of the land were turning 'Jewish," for the fear of Mordechai fell upon them!"
May G-d grant that each and all of you should go from strength to strength in emulating Mordechai the Jew, advancing in all matters of Yiddishkeit, Torah and Mitzvos, with joy and gladness of heart, and may you all be blessed with a full measure of " light, joy, gladness, and honor," both in the plain sense as well as in the inner meaning of these terms in accordance with the interpretation of our Sages - "Light - this is the Torah... honor - this is Tefillin," - since the Torah and Mitzvos, though a "must" for their own sake, are the channels and vessels to receive and enjoy G-d's blessings in all needs, materially and spiritually.
Wishing each and all of you a happy Purim, and may the inspiration of it be with you every day throughout the year,
With esteem and blessing,
(Excerpt of a letter dated Rosh Chodesh Adar II, 5738)
