a) Speech which isn't heard or accepted is not called speech at all. To rectify speech that it be heard and accepted is by praising, by praising the true tzaddikim. This is the general correction of speech.
b) When speech is without understanding, it doesn't contain good and then it isn't heard or accepted. But, by praise of the tzaddikim, one's understanding is raised and this instills good into the speech. When one receives speech from understanding it contains good; everyone desires good and for that reason it is heard and accepted.
c) The correction of speech, which is the 'Kingdom of the Mouth', is by the aspect of "white clothes" (Eccl.9). One has to guard one's clothes very much so as not to abuse them; you have to look after them properly so that they don't get stained or dirtied. Clothes are an aspect of Kingdom, then King of Honour, for Rebbe Yochanan called his clothes, "my honour"(Shabbat,113). This means that someone who abuses his clothes is like a rebel against the Kingdom. Then the judgement of the Kingdom judges him. Whoever is greater than his fellow has to guard his clothes more because in Heaven they deal with him more strictly. For this reason the Sages said that a Torah scholar who has a stain on his clothes is deserving of death, Heaven preserve us. (Shabbat,117).
d) If a person doesn't guard his clothes and gets a stain on them, through this he causes a separation between the Shechinah and the Holy One, Heaven forbid. As a result the disgraceful maid servant takes control, which means the Kingdom of Evil. This causes menstrual blood to the Shechinah, Heaven forbid, and this makes finding a livelihood much harder.
e) The wicked, according to the prohibition that they transgress, arouse and cause menstrual blood to the Shechinah. This causes a separation between the Holy One and the Shechinah, Heaven forbid. To rectify all the sins in detail is very complex and difficult for a person; it is impossible to rectify them because there are very many details and fine points in each prohibition. Therefore, a person has to rectify generally, all inclusively, and this is by rectifying the brit. By this, one automatically rectifies all the prohibitions that one transgressed. This rectifies even the very narrow and fine places (the sinews) where one can't reach other than by a general correction; this throws (arrows of) rectifications even to these places.
f) By this all inclusive rectification, which is the rectification of the brit, one elevates the brain. The essence of rectifying the mind is through rectifying the brit and this is the main way that Israel come closer to their Father in Heaven.
g) Finding a livelihood without effort depends on this for, by the rectification of the brit, one merits to the aspect of Manna, an aspect of the bread of a livelihood from Heaven. On the other hand, when a livelihood comes with great effort, this is because the person hasn't performed the all inclusive rectification of the brit. (See the Zohar,Pt.3,pg.244A).
h) All the time that a person hasn't rectified himself in this all inclusive way, speech is forbidden, as it says, "I was dumb with silence" (Psalms,39:3). By this the Schechinah is in an aspect of menstrual blood, Heaven forbid. From this menstrual blood of the Shechinah comes silence (in Hebrew, blood, 'dam', contains the same letters as silence, 'dumia'). This is because the essence of speech depends on the rectification of the brit, as it says, "and he declared his covenant to you." (Deut.4:13). Then it is impossible to speak and reveal Torah; whoever speaks then transgresses the prohibition of "don't go gossiping among your people" (Leviticus,19,16). He is "a talebearer who reveals secrets" (Proverbs,11:13). However, by the all inclusive rectification, speech is permitted and one can open one's mouth and reveal enlightening words of Torah.
i) Epilepsy is caused by the blemishing of the brit, Heaven forbid. Therefore, by rectifying the brit, one is cured from this illness.
j) When a person hasn't rectified himself generally and completely, he has to stay away from drinking wine because this leads to all of the sins. It also damages a person's livelihood and he is impoverished. However, someone who merits to the all inclusive rectification, on the contrary, he raises his brains through drinking and rectifiers himself even more.
k) Someone who doesn't do business with faith and is deep in the craving for money, and steals from his fellow, he arouses and causes menstrual blood to the Shechinah, like blemishing the brit, and he loses his livelihood, Heaven forbid.
l) The main way to rectify business affairs is to have in mind, every pace you take and in every word you say during business that your intention is to earn money in order to give charity. This is the general rectification of business matters, like it says, "Sow for yourselves charity" (Hoshea,10:12). This alludes to the white sperm (Tikkunei Zohar,52B) and that is an aspect of rectifying the brit. Through giving charity the brains are elevated and one gets an easy income.
m) Therefore through charity one can talk and speak out enlightening Torah ideas, as the Sages said, "In your mouth- this is charity." (Rosh Hashana,7). This is what it says, "The tzaddik gives with good grace" (Psalms,37:21) ; this is an aspect of the rainbow covenant, for the tzaddik guards the brit.
n) The rule from all these things is that one has to first make a general rectification that applies to him in order to fix and elevate the brains and draw from there whiteness, to fix and whiten all the blemishes. This is impossible other than by an all inclusive correction that is applicable to him such as doing business with the intention of giving charity. As a result of this, one elevates the brains and then everything is automatically corrected. That's to say, by the general rectification of all things, one raises the brain and draws all the whiteness. This is an aspect of 'the whiteness of the fluids of the brain that flow from Lebanon' (Zohar,Pt.3:72). By this, automatically, all the small details are also rectified.
o) A woman whose menstrual blood is excessive and she has no regular period, even though wine hurts her, being an aspect of increased blood, even so, her cure is to drink the wine that a true tzaddik looked at, for his holy eyes are an aspect of 'hairs' which are an aspect of extraneous matter from his holy brain. This draws the white fluid of the brain which whitens the blood, the menstrual blood, and thus it is rectified.
p) The thoughts in the mind of a person are according to his traits. In accordance to whatever trait a person is holding to, so the thoughts in his mind alternate and pass by, as it alludes to in the verse, "Seven locks of my head" (Judges,16,13). The locks of hair allude to the brain for hairs are excrement from the brains. When the seven attributes pass through the mind and hit the hairs, the power of sight is damaged for there are seven layers. (See introduction to Tikkunei Zohar,12). The opposite is also true; by rectifying the seven layers of the eye, one rectifies any blemish to the seven types of thought which are the hairs, an aspect of the correction of the brains.
