When he and Sita Ram Goel were fighting together against the menace of communism in India after 1949, Sri Ram Swarup viewed Gandhism as an alternative to communism. In a pamphlet written after the assassination of Gandhiji ' Mahatma Gandhi and his Assassin ' (1948), he expressed the view that martyrdom was only befitting a man of Gandhiji's elemental greatness.

After waging a relentless intellectual battle against communism and serfdom, Sri Ram Swarup turned to religious and philosophical issues after 1957. Apart from contributing a large number of seminal articles on Hinduism, Islam and Christianity from several points of view to important newspapers like The Times of India, The Indian Express, The Observer and Hindustan Times, he also wrote a series of important books on comparative religion and philosophy. Some of his main works are: Buddhism vis-a-vis Hinduism (1958), The Hindu View of Education (1971), The Word as Revelation: Names of Gods (1980), Hinduism vis-a-vis Christianity and Islam (1982), Christianity, An Imperialist Ideology (1983), Understanding Islam Through Hadis (1983), Hindu-Sikh Relationship (1985), Ramakrishna Mission in Search of a New Identity (1986), Cultural Alienation and Some Problems Hinduism Faces (1987), Hindu View of Christianity and Islam (1992), Woman in Islam (1994), On Hinduism: Reviews and Reflections (published posthumously in 1999), and Meditations: Gods, Religions (published posthumously in 2000).

Sri Ram Swarup was an unassuming, quiet and reflective type of person. He never sought a job; he never got married and he never did any business for commercial profit. After a life of strenuous and unremitting intellectual labour, Sri Ram Swarup passed away peacefully during an afternoon nap on 26 December 1998 leaving to the world a splendid example of lonely and disinterested pursuit of truth and light.

When Sri Ram Swarup's Hindu View of Christianity and Islam was published in 1992, Syed Sahabuddin, a Janata Dal Member of Parliament wrote a letter on 20 August 1993 to his co-religionist, the Union Minister of State for Home Affairs (Late) P M Syeed, asking the Government of India to have the book examined from the point of view of banning it under the law of the land. SYED SAHABUDDIN'S VILE ATTEMPT TO GET SRI RAM SWARUP'S BOOK HINDU VIEW OF CHRISTIANITY AND ISLAM BANNED BY GOVERNMENT OF INDIA IN 1993 FAILED MISERABLY.

An instantaneous reaction from Arun Shourie fully exposed the unfounded prejudice of Syed Sahabuddin in the whole affair and a statement made by a group of intellectuals, under the leadership of K S Lal against Syed Sahabuddin's proposal to impose a ban on that book also had the desired impact.

In their statement on that occasion these intellectuals declared as follows: "We strongly condemn all recent attempts in India and abroad to prevent free enquiry into the history and the doctrines of various religions. In particular we condemn the attempt by Syed Sahabuddin to make the Indian authorities impose a ban on the book Hindu View of Christianity and Islam by Sri Ram Swarup published by Voice of India, New Delhi in 1992. This book is one of the first serious comparative studies of religion written from the Hindu viewpoint; banning it would be a direct attack on the right of Hindu society to develop an intellectual response to ideological challenges."
