The Tantric Trick- The Tantric, rubs some Gurhal Flowers also called Jaswand and China Rose in the English language on his knife and then lets it completely dry up. He then asks the person who has come to him for help regarding some Tantric Solution regarding a paranormal problem to bring a Lime[ Nimboo].
As the unsuspecting seeker has himself purchased the Lime, he does not suspect any foul play as the Tantric mutters a Mantra and then cuts the Lime and a red colored liquid starts oozing out from the lime. This red colored liquid is a result of the reaction between the China Rose flower Juice on the knife and the Lime Juice. The unsuspecting seeker thinks that it is blood, which is oozing out from the lime and believes that the Tantric has solved his problem using most powerful Occult powers.
