First few weeks in the college are some of the most difficult days in the life of a student. He stays away from his family, he is encountered by a whole new set of friend circle, and is welcomed by a whole different culture of the place where the college is situated. At such a topsy turvy juncture the last thing the student needs is a ragging by seniors.
This creates a very bad image for some students and they may face it very different to face.
So the institution, teachers, wardens must take special care to avoid cases of ragging.
