The Book of Character
In this book, all the traits and conduct are arranged in aleph-bet/alphabetical order. It is divided into two parts that are known to us by the names "Aleph-Bet Old" and "Aleph-Bet New." The first part is a wondrous collection, collected by our pure and holy master in his childhood, all that his huge intellect perceived by understanding one matter from another; and he gathered from all the holy books, everything that he found in them pertaining to morals, conduct, and upright behavior -- which he recorded to have by him for memory's sake.

For everyone, when he sees arranged the utter derision of a bad trait and the great loss it causes, and the dreadful violation that is realized through it, he will have compassion on his soul, and he will gird his loins to stand up against it, and he will beseech from He to whom mercy is His, to escape with his soul from the abyss, to save him from those bad traits or bad desires or similar ones, and so in the converse regarding good traits.
