Edamaruku has been active in the
Indian Rationalist Association (IRA) from the age of 15. Before becoming the president in 2005, he served as the General Secretary beginning in 1983, and has been the editor of its publication
Modern Freethinker. His many books and articles deal mainly with rationalistic thoughts and against
superstition in India. His writings in
Rationalist International are translated into English, French, German, Spanish, and Finnish. In February 2011, Edamaruku was elected as a Fellow of the
Committee for Skeptical Inquiry. (USA) and is an Honorary Associate of
New Zealand Association of Rationalists and Humanists and
Rationalist Association of UK (formerly Rationalist Press Association). Edamaruku conducted investigation and campaigns in Indian villages, targeting mystics,
god men and practices he deems
superstitious. He has helped in building Indian Atheist Publishers, which is now
Asia's largest atheist publishing house. He convened nine International Rationalist Conferences held in 1995, 2000, 2002, 2005, 2016, 2017, 2019, and 2024. In December 2013, Edamaruku launched a new quarterly English language magazine
The Rationalist on his blog.
The Great Tantra Challenge On 3 March 2008, while appearing on a panel TV show, Edamaruku challenged a
tantrik to demonstrate his powers by killing him using only magic. This incident, though not recognised by the Catholic Church as a miracle, was believed by locals to be one. Sanal Edamaruku was invited to investigate by TV9 of Mumbai with the consent of the church authorities. He went with an engineer to the site where the alleged miracle had happened, and traced the source of the drip to the rear side. Edamaruku found that the water was seeping through the feet because of
capillary action and faulty plumbing. Moisture on the wall where the statue was mounted seemed to be coming from an overflowing drain, which was in turn fed by a pipe that issued from a nearby toilet.
Comments and aftermath During a television show held to discuss the investigation, Edamaruku accused Christian priests of regularly
scamming devotees and
defrauding miracles to make money, and build bigger and newer churches and convents, and the Pope of being "anti-science" and scoffed at Christians for worshipping the cross. A Catholic lawyer asked Edamaruku to apologise whilst on television, which he refused to do. Such
defamatory statements lead to the
Catholic Secular Forum filing
First information reports under
Section 295(A) of the
Indian Penal Code in April 2012. The
All India Catholic Union said the law was being applied incorrectly.
Colin Gonsalves, the founder of the India Center for Human Rights and Law, stated his opinion that no criminal offence had been committed.
Vishal Dadlani,
Richard Dawkins and
James Randi publicly spoke in Edamaruku's defense while others accused Edamaruku of being "as much of a missionary seeking converts for his particular “ism” as the Church is for its own belief." ==Views==
