Kabbalah for Deuteronomy 4:30

Rabbi Yitzchak (other versions Yehuda) said after him: "when you are in distress because all these things have befallen you and, in the end, return to Ad-nai etc" (Deuteronomy 4:30). "When you are in distress" - from here [we learn] that teshuvah is better than everything since judgment still rules in the world. Once judgment rules in the world, its force is strong, one who crosses it goes from this world, that, behold ...since Judgment rules one cannot go until one pays. Once one paid, and did teshuvah, one fixed all worlds. Meaning, since it is written "and those things will find you at the end of the days" (Deuteronomy 4:30) and it is written "and you will return to Ad-nai your God etc" because "Ad-nai your God is a compassionate God etc" (Deuteronomy 4:31)
