Puri Shankaracharya Swami Adhokshjanand Devtirath today said he will go to Varanasi and campaign against the BJP's Prime Ministerial candidate for the May 12 elections.
"I will go to Varanasi and expose him. Those who divide people to come to power should be exposed," he said.
He said Modi has committed "sins" and no justice-loving person can ever "like" him.
Modi is pitted against AAP leader Arvind Kejriwal and Congress candidate Ajai Rai in the holy city.
The Shankaracharya said he had himself gone to Gujarat and witnessed the situation after the 2002 riots.
He charged RSS with using religion to "mislead" the people. He said it should come to the fore as a political organisation rather than a social-cultural body.
The Shankaracharya said BJP leaders were already issuing statements which were creating tension in the country.
He said he would not campaign for any particular party but just wanted that secular parties should win.
Dwarka Shankaracharya Swami Swaroopanand is also opposed to Modi and will be deputing his close associate Swami Avi Mukteswaranand to Varanasi to campaign against Modi, sources close to him said.
They said he himself cannot travel to Varanasi because of his poor health.
Swaroopanand had recently protested against 'Har Har Modi' slogan, saying it amounted to "worship" of a man and "god will stop Modi" if it was not stopped.
Sensing a religious controversy, Modi had immediately asked his supporters to refrain from raising such slogans.
