The Rosh Yeshiva gives three reasons why teshuva (repentance) is the only way to be saved from Yom HaDin (the Day of Judgment).
The Rosh Yeshiva reflects upon the principle in Parashas Mishpatim (Shemos / Exodus 21:23-25) about appropriate mida keneged mida (measure for measure) din (judgment) when a person harms another person compared to the actual Jewish understanding and application of the related pesukim (verses), and the real purpose of the Torah.
