Having left off with the question of why Haman's evil plot was unsuccessful, the maamar now turns its focus to King Achashverosh. We learn that the level of divinity symbolized by Achashverosh refers to a transcendent plane where the categories of ends and beginnings lack any practical distinction. Consequently, the rule of Achashverosh was characterized by a time of seeming divine indifference, where evil appeared to have been allowed to prevail without incurring G-d's immediate judgment. Why then did Haman still feel the need to cast a lottery to carry out his plan?

Chapters 6 and 7 of the maamar.
