"Go on then -- kill me."

Your magic is weak, old man!

When a famous tantric guru boasted on television that he could kill another man using only his mystical powers, most viewers either gasped in awe or merely nodded unquestioningly. Sanal Edamaruku’s response was different. “Go on then — kill me,” he said.

Mr Edamaruku had been invited to the same talk show as head of the Indian Rationalists’ Association — the country’s self-appointed sceptic-in-chief. At first the holy man, Pandit Surender Sharma, was reluctant, but eventually he agreed to perform a series of rituals designed to kill Mr Edamaruku live on television. Millions tuned in as the channel cancelled scheduled programming to continue broadcasting the showdown, which can still be viewed on YouTube.

First, the master chanted mantras, then he sprinkled water on his intended victim. He brandished a knife, ruffled the sceptic’s hair and pressed his temples. But after several hours of similar antics, Mr Edamaruku was still very much alive — smiling for the cameras and taunting the furious holy man.

Guess he threw a temper tantra.
