These laws also exist in our world but only as a reflection of the upper laws of nature. Therefore, we speak only about their spiritual realization and, in no case, about the earthly one.
Kabbalists are engaged in the spiritual realization and religious people are engaged in the earthly one. Kabbalists and religious people disagree in this respect because religious people are engaged in the physical fulfillment of the laws of the Torah and not in their spiritual realization.
Question: It is written, “Cursed be he who lies with his sister.” What does “sister” mean from a spiritual point of view?
Answer: A person has many desires that he cannot correct in a direct way since he does not have a suitable screen. He must create a system for this and correct his desires with its help through subsystems that he forms within himself.
That is, he cannot directly influence his desires, which are called his various relatives such as his sister, his mother’s daughter, his mother-in-law, and so on.
These desires are being corrected and are represented in our relatives, especially those who are closer to us; relatives are subsystems in relation to a person.
