The Chozeh of Lublin asked, what’s the point of constantly doing teshuvah if a person continues to sin?! The answer, he said, is that through teshuvah a person gains an understanding of himself and his flaws. Another insight, another understanding....
When a person makes a reckoning of his deeds, he becomes tethered to the truth, and then everything around him is illuminated. The stamp of HaKadosh Baruch Hu is emes, אמת הקב"ה של חותמו — and so, when a person does teshuvah, everything around him receives the stamp of truth! When a person searches for the truth, and he seeks to see the world through the proper lens, the Ribbono shel Olam assists him in this. He merits great siyatta diShmaya.
