ט"קי
Tikunei Shabbos teaches that reciting chapter (Tehillim 119) ט"קי banishes the kelipos. Included in "kelipos" are our enemies and the yetzer hara. It is therefore very beneficial to recite this chapter. Some say it every day.
It states (Devarim 6:19), מפניך אויבך כל את להדף, "to thrust away all your enemies from before you."
How do you thrust away your enemies? The Or Pnei Moshe (Va'eschanan שבת בתקוני איתא ה"ד) says that this is done by reciting chapter 119/ט"קי of Tehillim. להדף is gematriya 119, and ת"א is roshei teivos for אפי תמניא, which means "eight phases," alluding to chapter ט"קי of Tehillim, which is called אפי תמניא because it contains eight pasukim for each letter.
The Or Pnei Moshe writes, "When one says this chapter often, it causes כל ת"א ף"להד אויבך , the enemies within us to become shattered and removed."
The Imrei Noam (יאמר או ז"ט אות) writes that before Yaakov Avinu met with Eisav, he said this chapter for protection. A hint is לפניו מלאכים יעקב וישלח, and לפניו is gematriya 176, and there are 176 pesukim in chapter ט"קי of Tehillim. The chapter begins with תמימי אשרי דרך , and Yaakov is called תם איש, as it states (Bereishis 25:27), אהלים יושב תם איש ויעקב.
When Yaakov wrestled with Eisav's malach, it states, עמו איש ויאבק, "a man wrestled with him," and ויאבק is gematriya 119. These are all remozim, hints, that this chapter helped Yaakov overcome Eisav.
As we wrote, some people say this chapter every day. If it is hard to say it every day, it would be a good idea to say it at least once a month. It banishes all enemies, the enemies outside us, and the enemy within us, the yetzer hara.
