Tikkun 21 – 88

Songs 8:7 “ מַיִם רַבִּים, לֹא יוּכְלוּ לְכַבּוֹת אֶת-הָאַהֲבָה, וּנְהָרוֹת, לֹא יִשְׁטְפוּהָ”
”Many waters cannot quench love, neither can the floods drown it”

Leviticus 17:13 “ וְאִישׁ אִישׁ מִבְּנֵי יִשְׂרָאֵל, וּמִן-הַגֵּר הַגָּר בְּתוֹכָם, אֲשֶׁר יָצוּד צֵיד חַיָּה אוֹ-עוֹף, אֲשֶׁר יֵאָכֵל–וְשָׁפַךְ, אֶת-דָּמוֹ, וְכִסָּהוּ, בֶּעָפָר”
“Any one also of the people of Israel, or of the strangers who sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with earth.”

The Torah instructs that when we take the life of an animal for the purpose of eating, we should cover its blood with earth. The souls in the pure animals are souls in the process of correction and should require special attention from us to help them.

Blood is דם, numerical value 44 and earth, עָפָר is 350. Together with the Kolel (adding 1 for the whole) it is equal to נשמה, which means soul.

The Zohar explains that the “Many Waters” refer to the water of the Flood and even though they brought death, they can’t disconnect the connection of our souls to the Creator.
The Shechina covers and protects us with love under her wings and bring the light of Mercy, Chassadim, to us.

When we cover the blood of the animal we act like the Shechina and bring mercy and Chassadim to the animal’s soul. This helps ascend to the next level in its correction process.

The sages tell us that if a soul of a person sees the Schechina after departing from the body, then it can’t go back to life.
The Shechina keeps the life force vibrated in our bodies, like the lungs sustain the heart.

The night before Yom Kippur is when we do Kaparot, which is transforming our negativity to a chicken that we circle around our head. It’s wing symbolizes the protection of the Shechina and the soul of the chicken accepts the process knowing that it will elevate her higher. We should look at the blood at the time of the actual slaughter with a consciousness that this will take the judgment from our life and bring us to Yom Kippur with mercy. Immediately after the blood drips down to the ground we should take from the dust of the earth and cover the blood with a special blessing to bring mercy to the soul that helped us become cleansed.
Some slaughterhouses that host the Kaparot process use saw dust. It may be good for covering and absorbing the blood but not for proper connection of bringing mercy to the soul as it should be.
