Forgetfulness is not, as is normally supposed, wholly an evil. It is rather a bliss to some persons, haunted by painful memories of lost friends, past misdeeds, failure in some things or other kinds of sad incidents. Some painful memories of past events can make us terribly sad at present. So it is better to forget them. If we remember all the tragic past incidents, we may be devastated by the unfortute memories. Then we will not have a moment’s peace. Hence it is better to forget them. Actually forgetfulness is a condition of memory itself, since it relieves the mind of unprofitable load and thus it makes the mind ready for fresh acquisitions.
