115. רַבִּי יִצְחָק אָמַר, כָּל מִי שֶׁנִּטְמָא בָהֶם, כְּאִלּוּ עָבַד לַעֲבוֹדָה זָרָה, שֶׁהִיא תּוֹעֲבַת ה’, וְכָתוּב לֹא תֹאכַל כָּל תּוֹעֵבָה. מִי שֶׁעוֹבֵד לַעֲבוֹדָה זָרָה, יוֹצֵא מִצַּד הַחַיִּים, יוֹצֵא מֵרְשׁוּת הַקְּדֻשָּׁה וְנִכְנָס לְרָשׁוּת אַחֶרֶת. אַף מִי שֶׁנִּטְמָא בַּמַּאֲכָלוֹת הַלָּלוּ, יוֹצֵא מִצַּד הַחַיִּים, וְיוֹצֵא מֵרְשׁוּת הַקְּדֻשָּׁה וְנִכְנָס לְרָשׁוּת אַחֶרֶת. וְלֹא עוֹד, אֶלָּא שֶׁנִּטְמָא בָּעוֹלָם הַזֶּה וּבָעוֹלָם הַבָּא, וְלָכֵן כָּתוּב וְנִטְמֵתֶם בָּם בְּלִי א’.
“כָּל עֲמַל הָאָדָם לְפִיהוּ וְגַם הַנֶּפֶשׁ לֹא תִמָּלֵא.”
“All the labor of man is for his mouth, And yet the soul is not satisfied.”
Rabbi Yossi explains the words of King Solomon who wrote Ecclesiastes, saying that Solomon with his superior wisdom reveals that when a person is judged in the world above, it goes according to the impurity he inflicted on his soul. When a person doesn’t watch his mouth from connecting to negativity, the court above takes revenge on him.
“And yet the soul is not satisfied” means that the soul worries that the judgment may not cleanse the impurity from her and she won’t be able to ascend higher because of the impurity that came from the other side.
Rabbi Yitzchak says that those who become impure by eating the forbidden animals considered as if they worship idols because they separate themselves from the side of life and holiness and move under the control of the other side. Furthermore, their impurity stays with them in this world and carried to the next.
The food we consume transfers the spiritual energy from the food into our bodies. Different body functions process the food, break it down and transform it into energy that spreads all over the body. The soul level of Nefesh resides in the blood that maintains the life force in every cell in the body. When the blood is contaminated with impure energy coming from the food, it affects the soul.
