On 3 March 2008, in a popular TV show, Sanal Edamaruku, the president of Rationalist International, challenged India’s most “powerful” tantrik (black magician) to demonstrate his powers on him.
Minutes turned to hours as the tantrik tried spell after spell against Sanal Edamaruku, attempting to kill or harm him. Live on TV (attempted murder in front of hundreds of thousands if not millions of witnesses?).
Of course, the tantrik failed. More here.
