While Marxist veteran V S Achuthanandan has already made it clear he would boycott the function, it was the turn of the CPI(M) state secretary Pinarayi Vijayan yesterday to attack the Mutt for rolling out the red carpet to Modi.
Vijayan said the sanyasins should not have invited Modi to the spiritual centre founded by saint-reformer Sree Naryana Guru, who preached the message of "one caste, one religion and one God for humanity."
The Mutt authorities, however rejected the criticism and maintaining that the doors of the ashram are open to all and the current controversy is unwarranted.
"Sivagiri Mutt has no politics and its tradition is to welcome all," said Swami Rithambharananda, who is president of the Sree Narayana Dharma Sangham Trust. The Mutt had also extended invitation to UPA chairperson Sonia Gandhi and AICC vice-president Rahul Gandhi but they did not respond, he said.
