They key in Rabbi Arthur Waskow’s Beliefnet essay on upcoming Purim is this:
In a new and deeper understanding of Torah, “blotting out the memory of Amalek” must come to mean something other than murder. The key to a deeper spiritual understanding is seeing that a spark of Amalek may arise not only in outsiders and enemies but also in our selves.
The “murder” he refers to is Baruch Goldstine’s killing of Palestinians during Purim 11 years ago. The “blotting” is the custom to drink enough to mix up thw words “blessed” and “cursed” and therefore remove the arch-enemy’s name. But the point is that we each have dark sides and potential to get drunk wtih blood. If we keep that in control:
When each of our peoples can anoint the others, we can all begin to enter the messianic harvest of our history.
