Question: What is the meaning of the verse “Take ye therefore good heed unto yourselves,” according to Kabbalah?
Answer: It means that a person has to be careful not to fall into his egoistic desires.
He has to make sure that he is constantly surrounded by the right society that will keep him in the correct altruistic direction and make him feel that developing in spirituality is important. The environment will always make sure that he perceives the feeling of the Creator in the Light of Hassadim, which is a very special force, the attribute of bestowal.
If a person continuously renews this force inside him, he will begin to ascend in spirituality and will feel the Creator at every moment, closer and stronger. This is called, “Take ye therefore good heed unto yourselves.”
