Kabbalah su Proverbi 19:3

And after that we made known to you this, because the essence of faith and basis of unification is to understand the uses of [the Hebrew is unclear, there is a manuscript brought in the Ramat HaSefer edition that reads: we need to go back and make known to you that the essence of faith and the base of the base is to understand and know all holy names] mentioned in the Torah are all contained in the four lettered Name, which is YHVH, blessed be, and that is called the body of the tree, and the rest of the names - some are root, some are branches, some are treasures and hidden, and each one of them has a specific activity that belongs to it alone. It is similar to a treasury that has several rooms, and each room is specific to what is inside; in this room precious stones and pearls, in this room silver, in this room gold, in this room all sorts of edible things, in this room all sorts of drinks, and in this room all sorts of clothing. And when a person needs something edible, and does not know which room has food, the person could die of starvation, and the rooms are all filled with good things, and the person died not because the request was denied, rather, is was because one did not know in which room was the needed thing. And the exact same way is the comprehension of the holy names of the Blessed one: there are names that are specialized for tefilah and compassion and forgiveness, and there are those for tears, and there are those for injury and difficulties, and there are those for food and sustenance, and there are those for grace. And if one does not know to concentrate during one's tefilah on the name that is the key to what one needs, who caused one not to be able to express one's desire? One's own foolishness and diminished comprehension. And regarding this it is said: "A man’s folly subverts his way, and his heart rages against Y"Y" (Proverbs 19:3). This is because Y"Y's hands are open to all, but a person's foolishness of not knowing in which treasure what he needs is, that person returns empty and thinks in his mind a bad thought, namely, that Hashem withheld from him his desire and his will - and this is not so, rather, his own foolishness of not knowing in which treasury is the thing he needs withheld it from him. And regarding this it is said: "your sins withheld the good from you" (Jeremiah 5:25). And therefore a person needs wander in the ways of Torah and to know the intention of the holy names, so that one will be an expert on them and on their names, and when one desires to request something in front of Y"Y of Blessing, a question and a request, one will concentrate on the name that is specific to one's question, and it is not enough to express all one's needs, rather, one should be beloved on high and pleasant below, and one will find oneself inheriting both this world and the world to come.
