He is a staunch supporter of Gandhian belief, ideology and teachings. As the office bearer of many organisations, he organised many movements to highlight Gandhian principles. The non-violence movement which he organised in 2009 lasted for two and half years against the closure of study centres of Adi Sankaracharya, Gandhiji, Narayana Gurudev, Chattambi Swamigal, Agamananda Swamigal, and Ayyankali. Inter-religious study centre was also closed by the syndicate of Sree Sankaracharya University of Sanskrit, Kalady. Prof. Peethambaran as the General Convenor of the movement organised more than thirty secular organisations to undertake Gandhian agitation against the wrong decision of the Syndicate. Silent agitation was completed in a phased manner and seventeen step by step movements were organised without any harm to property and people without affecting the normal working of the university. The Gandhian agitation was successful and the seven study centres were re-established. The movement was unique in the history of university agitation. Sanadhana Dharma Suhrut Vedi was the name of the confederation which commenced the Gandhian Movement. Many important personalities and social leaders took part in the deliberations of the silent movement.
As the State President of SRVCS, he led many Gandhian movements for promotion of the welfare of depressed classes and the downtrodden. He fought for social justice and all his agitations created a new culture in the field of movements for social justice. None of his agitation crossed the limit of ethics and his leadership was appreciated by one and all. The silent agitation in front of the official residence of the Chief Minister of Kerala was appreciated even by the authorities, a movement highlighting perfect discipline. A similar movement at Angamaly to call the attention of the Chief Minister of Kerala and yet another silent movement at Koratty in Thrissur district also were well appreciated by the authorities.

Some of the important such conventions were held at Angamaly, Ernakulam presided over by Sri K.K Viswanathan, Former Governor of Gujarat, Palakkad presided over by cultural leader Sri Sukumar Azhikod, Ernakulam presided over Justice K.K Usha, Former chief Justice of Kerala, Thrissur presided over Sri C.N Balakrishnan, the then Minister of Kerala, at Koratty in Thrissur district presided over by the then Minister P.P George.
