“וַיִּתְרֹצֲצוּ הַבָּנִים בְּקִרְבָּהּ וַתֹּאמֶר אִם כֵּן לָמָּה זֶּה אָנֹכִי וַתֵּלֶךְ לִדְרֹשׁ אֶת יְהוָה”
“The children struggled together within her, and she said, “If it is thus, why is this happening to me?” So, she went to inquire of YHVH.”
Rebekah felt an unusual activity in her womb and went to inquire with God about the strange behavior of her children and the answer came immediately.
Rav Huna says that the two children were the aspect of Liver and heart. They struggle to find who is the most important among them.
“וַיֹּאמֶר יְהוָה לָהּ, שְׁנֵי גֹיִים בְּבִטְנֵךְ, וּשְׁנֵי לְאֻמִּים, מִמֵּעַיִךְ יִפָּרֵדוּ; וּלְאֹם מִלְאֹם יֶאֱמָץ, וְרַב יַעֲבֹד צָעִיר”
“And YHVH said to her, “Two nations are in your womb, and two peoples from within you shall be divided; the one shall be stronger than the other, the older shall serve the younger.”
The two nations are the Heart and the Liver. The brain is not mentioned here because it’s in the head and not in the belly.
‘the older (Liver) shall serve the younger (Heart)’. The liver is big and serves the heart by removing negativity from the blood before the heart distributes it in the body.
The liver represents the world of Action, the material aspect of life and the body in general. The heart represents the spiritual aspect, which is the soul that keeps the body in existence, giving it ability to act. The Liver removes the ‘bad’ and the heart uses the good to ‘refresh’ the nefesh level in the body with pure life energy. When the blood circulation stops, the soul leaves the body.
Following the spiritual laws that the Torah gives us, keep the body and soul in a pure state while negative actions contaminate the body and soul up to a point of total darkness.
To cleanse impurities from body and soul, it’s good to do frequent fasting. One can get into this healthy habit by gradually train his body and soul for that. Skipping one meal a day for a while, then two meals a day, then just one meal in the evening. One or two days a week of daily fast is very healthy for people if they can handle it. Start by skipping meals and your heart and liver would be very happy.
