Tikkun 19– 31
Chokmah is called חיים, life, and the Chokmah of Arich Anpin is called life of life, where there is no death. Adam’s sin created a disconnection between him and all the levels above Binah.
He lost his spiritual “dress” and found out that he was naked (Genesis 3:7).
Because Adam ‘knew’ Eve before correcting the sin, the impurity of the Snake, attached itself to their connection. That resulted in a separation between the right and the left.
As a result Cain was born flawed and with a correction to make. He wanted to complete himself by overcoming the right side. Because he didn’t have the A א and Y י (See Daily Zohar #254), that are the source of life from Chokmah, he brought death on Abel, his brother.
