a) The main reason for the Creation was in order to know G-d (Zohar,Pt.2,42) as it says, "I created it for My glory…" (Isaiah, 43:7).
b) The body, in relation to the soul, is considered material, an animal, foolishness and darkness; an aspect of death and forgetfulness. It is like extraneous wisdom in comparison to the wisdom of the Torah which is the level of 'Man', as it says, "This is the Torah, a Man" (Num.19:14). Torah is an aspect of form, light, wisdom, memory and life. Every person has to subdue the materiality of his body, the aspects of death and foolishness of the body, which are the cravings; that's to say he must separate himself from all the cravings.
c) This is achieved by fasting which weakens the four basic elements of the body from which all the cravings stem. The materiality, foolishness, forgetfulness and darkness are subdued and nullified, while the intellect, form, and memory are strengthened and raised. This nullifies the harsh judgements and darkness and draws loving-kindness into the world. The main rectification of the fast day is by giving charity. It also subdues the extraneous wisdoms in relation to the Torah wisdom. One also merits to a good income.
d) There are two types of charity, charity in the world at large and charity in the Land of Israel. Charity that is given to the Land of Israel is greater and of more value than that of the rest of the world. There are also two types of Torah. There is no comparison between Torah that stems from the breath of a mouth of a sinner to that which comes from the breath of a mouth that has not sinned (Shabbat,119). For the harsh judgement is not sweetened, nor does the world continue to exist, other than on the breath of the children who have no sin. By them, the Patriarchs are revealed and they protect the world. By giving charity to the Land of Israel, you include yourself in the air of Israel, which is an aspect of holy breath without sin. This is the main way to nullify harsh judgements and darkness, forgetfulness and foolishness from the world. In turn, this leads to the subduing of extraneous wisdoms so that one merits to the wisdom of the holy Torah, to memory and light.
e) Therefore, every person has to ask and search a great deal for a pious, honest and G-d fearing Torah teacher and to ask a lot for this from the Holy One. This is crucial so the teacher won't spoil the holy breath of the children who learn Torah, upon whom the world rests. (Because of our sins, there are now schools that teach young Jewish children secular wisdoms which are foolishness and darkness etc. including foreign languages (as brought in the Lekutei Halachot, Pesach,7) and they cause impurity to the holy breath of the children, as we can see later on when they become atheists and non-believers. Happy is he who distances himself and his children from them. Our duty is not to send our sons to such places; it is forbidden to have any connection to them at all.)
f) One has to be careful to honour an elderly Torah scholar who, through no fault of his own, has forgotten his learning (Sanhedrin, 96). By the honour that we give him, we cancel his forgetfulness and his soul is revealed, which means his memory of Torah. Then the harsh judgements and darkness are nullified and we draw into the world, light, loving kindness, life and the wisdom of the Torah. This is because the root of Torah is the honour of the Holy One, as it says, "I created it for My glory…" (Isaiah, 43:7). About this, the Sages taught us, "There is no honour other than Torah"(P.Avot, Ch.6).
g) The main reason for the lack of income in recent generations is only that the ritual- slaughterers are not worthy. A ritual-slaughterer who is pious actually feeds and provides income for all Jews; he raises the soul that is re-incarnated in the animal to the level of 'speaker' (i.e. Man).This he achieves by the blessing that he recites over the slaughtering when said with great concentration. The slaughterer has to have in mind to raise the soul that is in the animal's blood. By this, the soul rises to the Shechinah, then the Shechinah unites (with the Holy One) and this brings an income to Jews. This is why the knife of the slaughterer is called 'ma'akhelet' which literally means 'feeder' (see Gen.22:6) because the worthy slaughterer 'feeds' all Israel. On the other hand, when the slaughterer is not worthy and even has undesirable thoughts when slaughtering, and doesn't focus his mind when making the blessing, he stands as a killer of souls and there is great anguish to the animal soul which cries out bitterly. Then his knife is a "sword of the wilderness" rather than a "sword of G-d"(Isaiah,34:6), a sword of the Shechinah and of speech, because it doesn't raise the re-incarnated soul, but, rather, pushes it down from the aspect of 'animal' and it doesn't find rest. Woe to such a slaughterer; woe to the soul who killed a soul and passed it over to its enemies; like this the Shechinah lacks the power to provide income. Through this, "We get our bread with the peril of our souls, because of the sword of the wilderness"(Lam. 5:9). With a great effort and bother we manage to get a little income because of his sword of the wilderness (which gave the soul in the animal over to the husks whose domain is in the desert, as is known.)
h) As a result of these slaughterers, the soul becomes subdued to the body and the material; then the bodily cravings become stronger. However, through the pious slaughterers, the soul is raised and the body is subdued, which is an aspect of animal and foolishness; an aspect of extraneous wisdoms. Thus, the soul and the form (spirituality) are elevated; they represent the wisdom of the Torah, and, by this, plentiful income is drawn into the world. This is what it says, "He has given food to those who fear Him" (Psalms, 111:5) and "Feed me my portion" (Proverbs, 30:8). In both verses food is referred to as 'teref' which alludes to 'trefa' meaning ritually unfit meat. This teaches that when Israel are careful to avoid ritually unfit meat, they merit to an income.
i) This is what it means, "be careful of the sons of ignorant people (to honour them) for from them Torah comes (Sanhedrin, 96). For it is known that precious souls are trapped in the husk of Nogah. The husk wants them to sink there so it puts the seed of such a soul into the sperm of an ignorant person; then this soul will become dirtied. It turns out that the sons of the ignorant are often precious souls, but they are like birds that are trapped in a net. How do we know of their beauty, only by their Torah, when we see that they are Torah scholars. By this, we know that they are precious souls. Therefore, we have to be careful to honour them because by this we reveal the Torah that is hidden within them. For the root of everything is the honour of the Holy One, as it says, "I created it for My glory" (Isaiah, 47). And the soul, which is the Torah, yearns to be included in its root, which is honour. Through this, Torah comes from them, the soul is raised together with the form and loving-kindness, etc. Then the cravings of the body and its materiality will be pushed off and all the harsh judgements nullified. Amen. So may it be.
