People with physical illnesses taste that which is bitter as sweet and that which is sweet as bitter, and there are some sick people who desire and crave foods which are not suitable for eating, such as dirt and charcoal, and hate good foods, such as bread and meat, all in accordance with the extent of the illness. Similarly, people whose souls are sick desire and love the negative traits and hate the good path and are indolent about following it, and it is extremely heavy upon them, in accordance with their illness. And so Yishayahu states regarding these people (Isaiah 5:20), "Woe unto them that call evil good, and good evil; that change darkness into light, and light into darkness; that change bitter into sweet, and sweet into bitter!" and about them it stated (Proverbs 2:13), "Who leave the paths of uprightness, To walk in the ways of darkness." And what is the cure for the spiritually ill? They should go to the wise, who are healers of souls, and heal their illnesses through the traits that they teach them, until they return to the path of good. And those who recognize their negative traits but do not go to the wise to cure them, about them Shlomo stated (Proverbs 1:7), "the foolish despise wisdom and discipline."
