I love magic, especially good magic. But all magic is a slight of the hand. and this guru should not be prayed too. Nothing he did was even decent slight of hand.

Look when he rolls his hands as he does repeatedly he's lowering necklaces down his shirt and likely pulling with an invisible string that has all of the necklaces on a string down from his backside as he is wearing a loosely fitted shirt. When he stops rolling his hands he's not only getting the necklace he's breaking it off from the rest of the chain. It's really not that complex and if you practice it enough you can probably give out 10-15 in a row on one string. And while the skeptic in me says that's kinda sad right it is also terrifying to me that this guy has children worshippers.
