The author investigates the public performances of Indian fakirs and yogis, describing common feats—mango-tree growth, basket and coloured-sands effects, diving duck, rope tricks, levitation, snake charming, and voluntary interment—and then explains practical methods that produce those effects. Each feat is presented as witnessed, followed by detailed, technique-oriented explanations invoking sleight of hand, concealed apparatus, prepared props, and natural properties of materials. The tone is skeptical and demonstrative, aiming to show how ostensible supernatural phenomena can be replicated by ordinary conjuring and physical means.
