Parshas Tzav starts off by commanding Aaron the Kohen Godol concerning the daily Mishkan service of Terumas Hadeshen, “Uplifting of Ashes”, taking a handful of ashes remaining from the overnight burning of the sacrifices on the altar and placing it near the altar in a special pile. This service was the first done in the morning and the last at night. However the actual language of the mitzvah begins with Zos Toras Ha’Olah, this is the law concerning an Olah sacrifice, which was offered as an entirely burnt offering. And then goes on to command that the fire on the altar should always burn, day and night. The entire section concerning the Mishkan service of Terumas Hadeshen must be connected. And I would like to posit that the connection concerns how we should act and serve Hashem, especially since the services and rites of the Bais HaMikdosh are no longer with us.
Chazal tell us that the Olah korban was generally brought to atone for impure thoughts. We learn this from the military campaign that Pinchos fought against Midyan after the Jews had sinned with the Midianite women. After the battle Pinchos brought sacrifices on behalf of the men in the army and said to Moshe Rabbeinu that they were being offered as atonement for any impure thoughts the soldiers may have had during the battle. Therefore all Olah sacrifices were to be burnt entirely on the altar, to connote that the impure thoughts were entirely rooted out of our minds.
The Torah teaches us how to lead our lives in a pure and holy fashion. Hashem knows that we are human with the frailties of a corporeal creature and an animal spirit existing together with a holy G-d created soul. And that this corporeal part may cause impure thoughts and actions. However we were provided by Hashem with the means of atoning and purifying ourselves. And we’ve been given the means to protect ourselves from impure thoughts, if we follow the dictates and life style that the Torah offers us. Chazal say that a person’s heart is a mini-Mishkan and mizbeach, altar. Besoch Libi Mishkan Evneh, within my heart I will build a personal sanctuary to Hashem and I will build a personal altar. The Torah that we learn, the mitzvos that we do, and our Torah lifestyle that we live, all of this can be compared to the wood that the kohanim placed on the altar during the day to ensure that the fire burns constantly.
Chazal tell us that we should make a cheshbon hanefesh, a daily accounting of our actions, each night before we go to sleep. Each morning we wake up and give thanks to Hashem for returning our souls. When we realize that we had impure thoughts, we should immediately do teshuva and “burn” these thoughts on our internal altar, in our internal mishkan. Burn, with what? With the daily Torah living and mitzvos that we’ve done, acting as the wood to burn away anything impure. And every morning as we wake up and give thanks to Hashem, we should also thank Hashem for giving us the means to atone. This is comparable to the taking of the ashes from the altar. We “lift up” the impure thoughts by replacing them with thoughts of Torah and yiddishkeit, actually “burning” away the impure thoughts. And the “ashes” that remain are then offered to Hashem as proof that we did teshuva.
Zos Toras Ha’Olah, the Torah that we learn and follow becomes the vehicle with which we can burn our impure thoughts. This is the Olah which burns on the altar all night with the flames of the mitzvos that we did all day. In the morning we can clothe our souls with the pure clothes of Torah living and then offer the “burnt ashes” of our impure thoughts to Hashem, who will then surely forgive us and provide us with the means to live a Torah life.
