Мишлей 23:9 Каббала: Ohr HaSekhel

Indeed, if a person reveals to you one secret, and you notice him being bewildered and astonished, thinking that the strength of his faith has departed from him, and he perceives you as foolish or a heretic, do not feed him the elixir of life, lest you kill him, and his soul is sought from your hands. Solomon already warned you about him, saying [Proverbs 23:9], 'Do not speak in the ears of a fool, for he will despise the wisdom of your words.' Do not overstep the ancient boundary that the predecessors established. According to this matter, you should examine the capacity of everyone who accepts a sophisticated or accepted matter and understand him according to what he is. The first secret you reveal to him should be from the easy matters that are on your lips, not from what is in your heart. What is in your heart should not be revealed to the public; in your actions, give each person his due, and follow the ways of the blessed Lord, who provides bread for all flesh and satisfies the desire of every living thing, willingly, as He desires, according to what one recognizes in Him. Endeavor in this matter to give to each person according to his ways and the fruit of his deeds. If instructive words that breach the fence emerge from your mouth, run quickly and repair the breach with him until his intention reverts to what it was initially. Employ strategy until he does not sense or comprehend your intention in any way. In this manner, you will be called a repairer of breaches.
