As a loyal servant in the presence of his master, I would like to latch onto the coattails of the Bnei Yissaschar and explain the rationale for HKB”H commanding every Jew to bring precisely “MAchatzis hashekel”—half a shekel—to the korbanos fund. As per the passuk cited above: “The wealthy shall not increase (give more) and the destitute shall not decrease (give less) from half of the shekel— to give the portion of Hashem, to atone for your souls.” Rashi comments: They (these shekalim) were used to purchase the “korbanos tzibur” of each year. The poor and the rich were regarded equally with regard to them. About that portion (donation), it says: “To atone for your souls,” since the korbanos come for atonement.
It appears that we can explain the matter based on a teaching from the Arizal (Eitz Chaim; Sha’ar 50, 7). He explains that we were commanded to bring animals as korbanos, because the animalistic soul is the one that sins. Additionally, in the Arizal’s Likutei Torah, in the Ta’amei HaMitzvos (Vayikra), he explains: "ולכן כשאדם חוטא, מקריב קרבן נפש בהמה של בעלי חיים, שהם גרמו לו לחטוא, ונחית אש גבוה ושורף אותן העבירות, ואז שורש נפש בהמי שבאדם נמשך לו ניקוי וזכות, כי הכל הוא משורש אחד חוצבו ומתכפר האדם". A sinner sacrifices an animal as a korban, because the animalistic soul caused him to sin. Thus, a heavenly fire descends and incinerates those aveiros. Then, the root of the animalistic soul in the person is cleansed and purified, because everything is hewn from one source, and the person receives atonement.
We will now introduce the brilliant, sacred words of the great Rabbi Chaim of Sanz, zy”a, in Divrei Chaim (Vayikra). Here is a condensed version of his inspirational interpretation of the passuk (Vayikra 1, 2): "אדם כי יקריב מכם קרבן לה' מן הבהמה מן הבקר מן הצאן תקריבו את קרבנכם"—when a person from among you will bring a korban to Hashem, from the cattle and from the flocks you shall bring your korban:
The matter of the korban is well-known. Clearly, the Almighty does not need to eat it. In His infinite wisdom, He issued this decree to bring a human being closer to Hashem. They of blessed memory explain that the kedushah of the fire on the mizbeiach consumes the material tendencies of the animal; this affects a corresponding change in the person’s animalistic soul. As a result of his teshuvah and contrition in the presence of Hashem while the korban is being sacrificed, the force the person’s animalistic force and tendencies are shattered and burnt. Thus, he connects with the force of kedushah . . . This is the implication of the passuk: “When a man from among you”—namely, that when a Jew offers a korban, he should have in mind to sacrifice a portion of his being to Hashem . . . Thus, the korban consumes the corruption of the animalistic soul within him and elevates the human portion within him to Hashem.
It is with great pleasure that we can now shed some light on the reason HKB”H commanded that we donate precisely a half of a shekel to the fund designated for purchasing all the “korbanos tzibur.” As explained, the purpose of offering an animal as a korban is to extinguish the negative, bad portion of the animalistic soul, which is closely associated with its good portion. Thus, the good portion can be elevated and devoted to Hashem. Therefore, we bring a “MAchatzis hashekel” specifically. For, as we have learned from the Bnei Yissaschar the gematria of שק"ל equals נפ"ש. This alludes to the animalistic soul from “klipat nogah.” It is our duty to separate the “MAchatzis hashekel,” its good, positive portion as "תרומה לה'"—a portion devoted to Hashem. So, by purchasing animal sacrifices with these funds, it enables us to incinerate the bad, negative portion of the animalistic soul and offer the good portion to Hashem.
