Kabbalah sur Les Proverbes 2:19

The wise Rav Yehuda Chagluah also wrote in his book ‘Tzafenat Pa’aneach’ that when it says that there is no Teshuva for him it means that his Teshuva is very difficult, and it is not enough for him to do Teshuva since he needs much infliction. And he does not have Teshuva means if he does not do all that is required for him to do. It is like what the sages teach about the verse “None that go unto her return, neither do they attain unto the paths of life” (Proverbs 2:19), which refers to a Non-believer that it is difficult for him to leave his ways.
