Chasidut su Proverbi 16:32

The Hebrew terms for mind, heart, and liver are moach (mind), lev (heart) and kaved (liver). An acronym of the terms is melech, literally, “king.”¹⁶⁰Words in the Hebrew language have many layers of meaning. In addition to the literal meaning of the words, the letters of a word might refer to a complete sentence. This occurs when each letter in the word represents the opening letter of a word in a phrase. Thus a three-letter word is in truth an acronym for a three-word phrase. This process is called roshei teivos, “beginning of words.” When man lives a life of mind first and then heart and liver, he is king over his lower self.¹⁶¹A king can rule others if he first asserts total dominion over his lower self. This unity between king over others and self-control was clearly expressed by Rabbi Yehudah Ha-Levi in his Kuzari, which is a record of a discussion between a Gentile king and a Jewish scholar.
Al Khazari: Give me a description of the doings of one of your pious men at the present time.
The Rabbi: A pious man is, so to speak, the ruler of his country, who gives to its inhabitants provisions and all they need. He is so just that he wrongs no one, nor does he grant anyone more than his due. Then, when he requires them, he finds them obedient to His call. He orders, they execute. He forbids, they abstain.
AI Khazari: I asked you about a pious man, not a prince.
The Rabbi: The pious man is nothing but a prince who is obeyed by his senses, and by his mental as well as his physical faculties, which he governs corporeally, as it is written, “He that ruleth his spirit is better than he that taketh a city” (Kuzari, Part 3, quoting Prov. 16: 32). Frequently, we reverse the order. Our lusts lead. For example, we desire someone else’s money, or we are lazy and seek to avoid performing a moral duty. We then arouse our heart to love that path and we employ our mind to rationalize and justify misbehavior, saying, “He did not need that money anyway. I will use it for better purposes than he,” or, “The duty will be performed by someone else, I can safely ignore it.” In these instances our livers were really first, followed by the heart, and then the mind. The first letters of kaved, lev, moach (the reversed order) spell kalem, which means, “embarrassment, shame, and death.” A life in which lusts rule inevitably ends with this unholy trinity.¹⁶²Da’as Tefillah pg. 273.
