בעזרת ה' יתברך-יום ד' פ' בא, ג' שבט, שנת תשע"ט
The holy Rebbe says (Likutei Maharan chelek 1, siman 169): “The core reason one sins in פגם הברית is, because he feels miserable and depressed.”
Depression only brings misfortune to a person, therefore be happy with a strong determination, and push away the misery from yourself. Don’t fool yourself; self-doubt and feelings of uncertainty, don’t originate from the Kedushah. Thoughts whether you are worthy in Hashem’s eyes; thoughts whether you will have a Tikkun or not; these are not holy thoughts, this is a trap of the Yetzer Hora to distance a person from Hashem.
Instead of thinking of yourself, or speculating if you are worthy or not, put your ego aside and start doing Avodas Hashem. Regardless of your current status; whether you are feeling significant at the moment. What difference does it make? Instead of feeling worthless and agonizing for days after Chas Vesholom committing an Aveira, instead of becoming depressed, have Hashem on your mind, and find ways to continue bringing pleasure to him.
The holy Rebbe said (Chai Maharan 453): “Even if I would transgress on the greatest Aveira; it would not break my spirit; I would continue being as Ehrlich as I was; and I would immediately do teshuvah.” One must not let himself be demoralized from anything in the world; even if he occasionally stumbles; one should not be influenced by his failings, instead one must continue serving Hashem, and do Teshuvah for his Aveira.
Go to Shul and Daven with Minyan; don’t keep pushing it off for later; don’t start your day before you don Tallis and Tefillin.
