When we build ourselves in the middle line, we must connect the property of bestowal, Bina, the right line, and the property of reception, Malchut, the left line, correctly. Their unification forms a Kli (vessel) called a “cave,” and this cave is double (Machpelah). In the “earth,” Malchut, there is space suitable for living, while life is Bina.
But before Bina can enter Malchut, a reverse action has to take place: Malchut has to enter Bina for Bina to know how to accommodate Malchut and for Malchut to know how to demand Bina’s participation. As a result, mutual penetration of Malchut and Bina or a “double cave” gets formed, and it is the foundation of the general correction of the created being.
Since this is the place of correction, the forefathers, the desires corrected by the intention to bestow, reside in it. They had attained the correct connection of Bina and Malchut: They receive in Malchut and bestow to Bina, meaning that they work with reception and bestowal.
But what gets buried? We bury the intention to receive that envelops the desire like a shell (Klipa), thereby turning it into the evil inclination. Therefore, burial is regarded as the act of correction.
We don’t touch desires: The greater they are, the better. But at each degree, or in each generation, we bury the “intention to receive for self gratification” and get corrected by establishing balance between reception and bestowal.
