Przysłów 9:4 Kabała: Zohar

For the Torah has warned them saying: “Whoso is simple let him turn in hither; as for him that is void of understanding (lit. heart), she saith to him” (Prov. 9, 4). Why is he called “void of heart”? Because he has no faith; since he who does not study the Torah has no faith and is wholly blemished. It is the supernal Torah which “saith to him”, and calls him “void of heart”.

As we have laid down, it behoves the sons of men to take due thought of divine worship and to labour in the Torah day and night, so as to know how to serve the Holy One, blessed be He. The Torah herself summons man daily, saying: “Whoso is thoughtless, let him turn in hither, etc.” (Prov. 9, 4-6).

Friends friends! Open your eyes wide that ye may see more clearly, for I know that at present ye imagine that such bodies are mere figures in the void, incapable of sustained existence. It is, however, not so, and ye must beware of such thoughts.
