If going to yeshiva solved our problems this forum would be little more than a Gmail chat.
Here is a short explanation of the Tikkun Kloli. I hope it is informative.
The whole world is built on ten sefiros: Keser, Chochma, Bina, Chesed, Gevurah, Tiferes, Netzach, Hod, Yesod, and Malchus. The Gemora in Pesachim 117 says that sefer Tehillim is composed from ten expressions of song,which we learn from the Zohar Hakodesh correspond to the ten sefiros.
Any collection of ten chapters of Tehillim which contain all ten expressions contain the essence of the whole sefer Tehillim and several mekubalim compiled lists of ten chapters of Tehillim containing all ten expressions to say everyday as a segula for various things.
It was also known that there are ten specific chapters which would fix the pegam of zera levatolo which is pogem in all ten sefiros, and many mekubalim tried to find them to help people fix their aveiros. Hashem did not want to reveal this secret until He decided that the time was right. He revealed it to the tzadik Rebbe Nachman of Breslov zt”l, a great-grandson of the Baal Shem Tov zt”l. The ten chapters are 16, 32, 41,42, 59, 77, 90, 105, 137, and 150. Since they fix all ten sefiros, they fix every pegam and every sin and therefore they are called Tikkun Kloli, the All-encompassing Remedy.
Rebbe Nachman zt”l explained briefly how they work and the great mekubal Rav Yitzchok Meir Morgenstern shlita explains at length how they work according to kabbolo in his sefer, Yam Hachochma.
The Tikkun Kloli cannot take the place of teshuva, but after one has toivled in a mikva, the Tikkun will remedy all the damage that was done. The Tikkun takes about ten minutes to say and is effective even if one does not understand the words, like all Torah shebiksav.
For the sake of honesty I want to say that I did not write this to answer your question. I wrote it a few months ago for my thread in the Bais Medrash and copied and pasted it here.
