Answer: Haman is our simple, straightforward egoism: I want, I need. “I want to rule over everyone, I want to be great, I want to…I-I-I.” Moreover, it’s not simply the egoism with which we were born but the egoism that we cultivate in the group.
When we start treating each other nicely in the group, preparing meals together, studying together (we are good guys, we are friends), suddenly something unexpected explodes between us: distrust, rejection, and hostility. This is the secondary egoism that appears as a result of our attempts to get closer to each other, and it’s called “Haman.” We need to reveal it as much as possible and not to be afraid of it.
That is why it’s necessary to prepare ourselves for the fact that there are very serious revelations of egoism ahead of us that work against our connection of unity in a single Kli (vessel) in which we can reveal the Creator. That is, this is the egoism that is clearly directed against the Creator.
