When I say placebo,it means that it just helps you "feel" a particular way(negative or positive).Like say when you do a tantric ritual for well being,you tend to feel that you're getting better even though nothing really happens

Is Tantra just a placebo or is it powerful?

Here is a video clip of Tantra challenge given by Sanal Edamaruku with a Tantrik.Sanal is the president of Rantionalist association.The tantrik says that he would kill him using his tantra.This was aired on India TV on 2008

The tantrik tries so many mantras and rituals but fails.Sanal ended up coming hale and healthy after the challenge

Here is the video

Is tantra really powerful or just a placebo?
