It is a compliant regarding what Rajinikanth said to his fans in Coimbatore. The complaint is lodged by a group of Hindus.
The banner at the meeting that was hanging behind him said "Kadamayai sei, palani ethirpaar" which means "do your work and expect the results". This is a saying for the great book of Bhagavath Gita.
Actually Bhagavath Gita says "Kadamyai sei, palanai ethirpaarathe" which translates into "do your work, don't expect the results".
The group who has taken this as an insult to the great book of Bhagavath Gita has plans to protest against him, demanding an immediate apology from the superstar.
