Why is contact with the dead prohibited to kohanim?
Why would Divine Providence create a kohen with a congenital mum-blemish; that disqualifies him from serving?
The Megadeph was apparently motivated by the holy yearning to “belong” to K’lal Yisrael-the Jewish People. Why was he so severely punished?
[Still, in spite of the kohen being physically blemished] he may eat the bread [i.e. food sacrifices] of his G-d, both from the holy of holies, and from the holy. But he shall not come to the cloth partition, nor approach the altar, for he has a blemish … Â
—Vayikra 21:22,23
 And the son of an Israelite woman, whose father was an Egyptian man, went out among the children of Israel; and the son of the Israelite woman had a quarrel with a man of Israel in the camp. And then the son of the Israelite woman blasphemed the Name, with a curse. The people brought him to Moshe[’s court]. And his mother’s name was Shlomis, the daughter of Divri, of the tribe of Dan.
—Vayikra 24:10,11
 the son of an Israelite woman…went out: Where did he go out from? … He “went out†of Moshe’s court [with a] losing [verdict. How so?] He came into the encampment of the tribe of Dan [attempting] to pitch his own tent. So [a man of this tribe] said to him, “What right do you have to be here?†Said he, “I am of the descendants of Dan,†[claiming lineage through his mother] he said to him, “[But Torah says (Bemidbar 2:2): ‘The children of Israel shall encamp] each person near the flag-banner bearing his paternal family’s insignia,’†[thereby refuting his maternal claim]. He entered Moshe’s court [where his lawsuit against the tribesmen of Dan was tried], and he “came out†defeated. Then, he stood up and cursed. (Vayikra Rabbah 32:3)
—Rashi Ibid
 Rabi Eliezer son of Rabi Shimon was coming from Migdal Gedor … and was feeling … elated because he had studied much Torah . There he happened to meet an exceedingly ugly man who greeted him, “Peace be upon you, Sirâ€. He, however, did not return his welcome but instead said to him, “Empty one, how ugly you are! Are all your fellow citizens as ugly as you are?’’ The man replied: “I don’t know, but go and tell the Craftsman who made me, ‘How Ugly is the vessel which You have made’ “.
—Taanis 20 A-B
 As it was taught, Shimon HaAmsoni … interpreted every [word] “es†in the Torah; [but] as soon as he came to, “You shall fear [es] HaShem your Elokim†he abstained [from interpreting the word]. His disciples said to him, “Master, what is to happen with all the esin which you have interpreted?†[Stumped by how to interpret the current ‘es’ Shimon HaAmsoni renounced the legitimacy of all his prior es readings. He taught his students … ] “Just as I received reward for interpreting all these words so too will I receive reward for retracting them [my elucidations.]â€

In Parshas Emor the Izhbitzer concentrates a great deal on the issue of תרעומות כלפי מעלה tarumos k’lapee ma’alah–grievances against G-d. When comparing and contrasting the Izhbitzers understanding of the kohen ba’al mum–who is physically blemished or disabled; and the Megadeph-he who cursed; i.e. the defeated litigant in a lawsuit in Moshe Rabenu’s court who cursed G-d; we find that their diverse approaches to tarumos addresses a trait central to the core of Jewish identity.
When a kohen becomes tamei-ritually impure; more often than not the cause is his carelessness or other human error. Moreover, being tamei is a temporary condition. In cases of tumah-ritual impurity; there is no permanent loss of the privilege of serving HaShem in the Mikdash. While a kohen tamei may be miffed at losing his turn at serving in, or even entering, the Mikdash, relatively speaking it is easy for him to accept and come to terms with his disappointment and frustration. However, many of the physical blemishes or disabilities that render a kohen a ba’al mum are congenital birth-defects. A kohen ba’al mum places the responsibility for his permanent ineligibility to perform the Divine service in the Mikdash squarely on Hashems shoulders kivyachol-as it were. After all, as in the case of the ugly man whom Rabi Eliezer verbally abused, the kohen a ba’al mum considers HaShem “the Craftsman who made meâ€. He is bewildered over why his Creator/ Craftsmen would have brought him thisclose to the Divine Mikdash service by having been born into the patrilineal Ahronic line yet, ultimately, excluded him and distanced him from Divine Mikdash service through “crafting†a “defective productâ€. In short, the kohen ba’al mum bears tarumos-heartfelt grievances; towards G-d.
The Izhbitzer understands the mitzvah addressed to the kohanim ba’alei mumim of eating of the korbanos– sacrificial offerings; as a way of appeasing them and addressing their tarumos. Their pnimiyus-their inner essence; even physically, is equivalent to all other kohanim. While the kohen ba’al mum may be blemished externally and superficially, his inner core lacks nothing. More pointedly; his internal organs become another vehicle for intimacy with HaShem. HaShem is Just and determines precisely how many kohanim ba’alei mumim there must be and which particular souls will be implanted into these “defective†bodies. Through the mitzvah of eating of the korbanos the kohen ba’al mum achieves intimacy with the Divine and, while being kept at arm’s length, kivyachol, in terms of service in the Mikdash, comes to realize that this too is a fulfillment if HaShems Will. In achieving this consciousness the bitterness of his tarumos are sweetened; transformed into wistful, brokenhearted yearnings for the closeness achieved through service in the Mikdash. In turn these yearnings engender the closeness and intimacy that HaShem has with the heartbroken “HaShem is close to the brokenhearted†(Tehillim 34:19 cp Zohar VaYesheiv page181A)
In contradistinction to the letting go of tarumos of the kohanim ba’alei mumim; the Megadeph allowed his tarumos to become his undoing. Per the Izhbitzer the inclusion of the narrative of the Megadeph in the Torah is only to serve as a cautionary tale of just how much we all need to rid ourselves of tarumos k’lapee ma’alah, even those rooted in the most noble of yearnings.
