Speaking to reporters, the priest said that if the idols could be adorned with blankets during winter then it was only normal to protect them from the pollution by using masks. 

The priest also claimed that the devotees visiting the temples have also started wearing masks after seeing the idols. He was of the belief that this move of adorning the deities with masks was raising awareness among adults and children alike.
