This is totally stupid . Gita has been modified and added with few clauses by a group of opportunistic people who have potrayed themselves as the upper castes and gave it the colour of religion and put it in the modified Gita for authenticating their claims . These people can put words on Lord Krishna's face in order to take advantage of the society. Unfortunately due to fear common people sometimes looses their common sense and gives much more importance than it should have been to some stupid religious rituals and sayings.
