Karma, for those who believe it, is a simple equation that explains how the universe functions – where there is cause there is effect. Each and one of us are governed by the laws of Karma.
For a mishap to happen to somebody, that person would have done something in the past to deserve it. If I dedicate my life to helping others, sharing and spreading positivity to the world good things will come back to me and the same works in reverse. When something extraordinarily good happens to a person and you attribute their success or good fortunes to the great work that they have done it is socially acceptable. However when something extraordinarily bad happens to a person and you attribute their misfortunes to bad deeds that they have must committed it is socially a taboo.
The students at Chinese University Hong Kong have expressed publicly the social taboo that should have been kept to themselves; even though what they were saying effectively implied that for such a misfortune to be bestowed upon somebody – that somebody must have committed some grievious deed to deserve such a retribution – i.e. losing a son. Regardless of what happened – only she will know what she did and it is not for outsiders to speculate.
