Answer

Excellent, excellent indeed. Credit is due to the gentleman, who has delighted me as every year, fed me from his bread and given me to drink from his wine—the perfumer's wine and the juice of his pomegranates—even before I have come to savor, as substance itself, the vintage of Purim, where what is permitted was absorbed and the lower force prevailed.
And so as not to leave the page blank, I shall add some little grain of my own, and may it be God's will that I say something acceptable. For I was wondering just now whether reading this gentleman's Torah insights is a positive commandment of Purim eve, like eating on the eve of Yom Kippur, or perhaps it serves as a prerequisite permitting the reading of the Megillah—such that there is actually a prohibition against reading the Megillah without first reading his words, may he live long, beforehand. And one could bring a proof from the fact that if it were a prerequisite, then we would be casting aspersions on the earlier generations, before this gentleman's wellsprings spread outward—for how did our holy forefathers, of blessed rest, read the Megillah without that prerequisite? Let such a thing be buried and not spoken. We are therefore forced to conclude that it is a positive commandment, and not a permit removing a prohibition.
However, one can also take an axe to that side too—that it is a positive commandment—for behold, the earliest of the early ones, in the First Temple period, how did they fulfill their obligation of the Megillah before the institution of the Megillah reading had even been enacted (as is evident from Lot's commandments, and these matters are ancient)? It is thus clear that we are not concerned about casting aspersions when it comes to a positive commandment, and from there infer and apply it to our case.
And with this we conclude that it is indeed a positive commandment, and it follows that the gentleman is among those who bring merit to the many, shining like the radiance of the firmament and like the very heavens in purity; and he has even merited to violate "do not add," like Jeroboam's calves, having invented a commandment out of his own heart.
And I shall conclude with a layman's blessing, which should not be lightly dismissed. May it be God's will that his domain increase through students; may his house be a gathering place for sages; and may he enjoy abundant holy satisfaction from all that is his, and from his wife—"among women in the tent may she be blessed"—whose signature has scarcely departed from beside his own signature (though this requires further analysis regarding the second booklet, and perhaps it escaped his notice). And through this, with God's help, may they merit to publish their words in these pamphlets called Tehumin, HaMaayan, or Asif, and the rest of the writings mentioned earlier that save from fire—those who are careful, in accordance with the custom of our holy rabbis, not to publish a woman's Torah thoughts without her husband, and who are not concerned with the dictum that "a wife is like her husband," but are stringent in accordance with the view that "a husband is like his wife"—examine this carefully.
