The science behind pratikraman (asking for forgiveness with repentance) is that you can ask for forgiveness for hurting someone without even saying a word and it will be considered true repentance.
You might ask yourself, is this kind of repentance possible? Yes, even if you are physically away, you can remove the feeling of difference between you, by using the scientific process of bhaav pratikraman (reversal of aggression in thoughts, speech and action by changing the inner intent). This means that you no longer have to carry feelings of hurt around with you because true repentance has occurred.
