Why we should forgive?

Once in a classroom, a teacher while teaching the lesson of forgiveness to the students gave them a task to be done in the entire week. She told all her students to take time and think of those people whom they have not forgiven in their lives. Then count the number of people and each person will be equal one potato. Then put the potatoes in a plastic bag and carry it everywhere you go, was said by the teacher to the students. The students obeying their teacher's words, carried their bags everywhere. Some students had 20 potatoes, while some had 32. As days passed, the students realised the motive behind it. They understood the weight of the the people they haven't forgiven is too much and we carry it everywhere, everytime. The plastic bag interrupted their work many a times and they were fed up with the bag. The moral behind this story is that we should forgive people no matter what. Some or the other day, they will be of our help. Not forgiving them will stop us from working effectively. They will become a barrier in our life everywhere, eveytime. Friends, forgiving people might not be easy. But yes it is possible. Bury the hatchet and live a happy life.
