ספר שיחות מוהר"ן אות - רצד

I heard in his name regarding the strengthening of prayer: that even if the person is as he is — even so he should strengthen and fortify his heart to pray to Hashem Yisburach. And he said that one should think in one's heart: Is it not true that I am so very far from Hashem Yisburach — because of the many transgressions and the great distance I feel from holiness? If so, specifically because of this I have even more need to pray and plead before Hashem Yisburach. For when a person is sick — specifically then he is in greater need of a doctor. And if one is not sick, one has less need of a doctor. So too in this — specifically because I am far from Hashem, I have more need to pray and plead before Him. For Hashem Yisburach is the doctor of souls, and the further I am from Him the more I need Him, and the more I need to pray before Him. And also: specifically the Holy Blessed One desires greatly to hear the prayer of the completely wicked more than the prayer of a complete Tzadik. For the Tzadik is already before Hashem Yisburach, and Hashem Yisburach is with him. But the wicked who is very far — when he cries out to Hashem Yisburach it is a greater novelty and a very great and precious thing before Hashem Yisburach. Therefore — specifically one who knows about himself that he is far from Hashem Yisburach should strengthen himself greatly to pray and cry out to Hashem. For this is the most precious before Hashem Yisburach.
