‘it shall remain seven days with its mother’
After the animals pass one Shabbat, their soul is ‘activated’ with the light of Shabbat.
“וַיְכַל אֱלֹהִים בַּיּוֹם הַשְּׁבִיעִי מְלַאכְתּוֹ אֲשֶׁר עָשָׂה וַיִּשְׁבֹּת בַּיּוֹם הַשְּׁבִיעִי מִכָּל מְלַאכְתּוֹ אֲשֶׁר עָשָׂה”
“By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done.”
The Zohar explains that on the seventh day God completed the process of Creation and ‘blessed’ the seventh day, which is the action of bringing the light from Binah to the entire Creation.
Genesis 2:3 “Then God blessed the seventh day and sanctified it”
Without the Shabbat’s light, nothing can be considered complete.
“וָאֶעֱבֹר עָלַיִךְ וָאֶרְאֵךְ מִתְבּוֹסֶסֶת בְּדָמָיִךְ וָאֹמַר לָךְ בְּדָמַיִךְ חֲיִי וָאֹמַר לָךְ בְּדָמַיִךְ חֲיִי”
“When I passed by you and saw you squirming in your blood, I said to you while you were in your blood, ‘Live!’ Yes, I said to you while you were in your blood, ‘Live!’”
A child is born with animal soul to give him life force. After the first Shabbat the soul is awakened. After the circumcision the Shechina pass by him and when she sees the mark of the covenant she bestows on the child light of Ruach.
This verse is said during the circumcision ceremony. The Hebrew word for ‘blood’ in the above verse, ’ דָמַיִךְ’ is in a plural form. It reminds us of the blood of Passover that the Israelites put on the threshold of their homes. It was done to protect their life from the killing of the first born. The second blood is the blood of the circumcision that is the first precept given to Abraham connecting him to the higher light.
The Zohar explains here that there are two aspects of blood during the circumcision, one is the blood that comes out when the father or the appointed Mohel cut out the foreskin that is the aspect of the Klipah that covers the head of the penis that is the aspect of Yessod. The second blood is when the Mohel performs the Periah, ‘פריעה’, which is the revealing of the penis head with his sharp nails.
These two steps are the second and the third of the four steps of the circumcision process that removes four types of Klipot from the child.
