Sri Sri Muralidhara Swamiji
Though water and ghee are basically liquids, when poured on fire they have opposite actions. Ghee stimulates the fire whereas water extinguishes it completely. It may appear that both worldly matters and the Divine Names are "thoughts'. While worldly matters expand the mind("manadhai vallarkkum"), the Divine Name of God destroys("manadhai azhikkum") it taking one to self-realization.

So a poster was requried which would stop many dirty posters being pasted. By Chanting and listening to Divine names of the Lord various unwanted thoughts that arise and disturb our mind are erased out and new ones do not crop up.
