"Kaliyug must also have its say." (not my words)
He is one of the agents of Kaliyug, the polluter of minds.
I recall one of his many 'stunts', that being calling some religious leaders to share the dais with him, under the guise of 'world peace and equality of religions', something like that, i think during the beginning of his 'career'. Sri Ravishankar was the one who had accepted his invitation one of those days. without losing much time, ZN quickly stooped down to his trademark-level, and the meet unveiled its true purpose - ridiculing & denigrating others and their beliefs, though yes, in a little sugar-coated manner.
SR later went on record, in a detailed interview of sorts, lamenting his decision to accept the invite, and detailing how that swoon resorted to verbal gymnastics to enthrall the zombie-audience and feed their collective superiority complex, engaging in smearing tactics. SR was literally caught off-guard on the stage, trying to make out what the hell was happening! he expressed disagreement there i think, and the next day or sometime later, in a public meet, expressed regret to have gotten trapped in the treachery of such a charlatan.
can't blame him. during those days, even i was pleasantly surprised and used to wonder about ZN, thinking of him to be some scholar attempting to unite people, until of course, i watched a video or two of his. there's a big ground here at Mumbai, which used to be reserved for his feed-the-zombies shows. since then, many print and visual media debates later and calls for banning his TV channel and shows, he's still continuing attacks on people's psyches, unabated i guess.
