Mandhiramavathu Neeru is a Thevaram song . It chants about the greatness of Thiruneeru. So beautifully it is named as Mandhiramavathu Neeru. Because the Neeru that is the holy ash is everything , it depicts that we all would be ash one day or the other, so one should be very simple , honest, and free from jealousy in life. Each one is unique, so do not compare oneself with others and be in complex and jealousy. To get rid off jealousy think of the holy ash and become pure and wipe of the impurities in ones mind.
