The masses have always been suspicious of Brahminical mambo-jumbo but this might be taking it too far:
Lokayata is a school of ancient Indian philosophy and one of three non-orthodox schools of thought. It is popular mainly among lower classes. In ancient Chinese text, it is also known as Lokaayatika, Carapace and the like. It has a very old origin and began to exert an important influence around the 6th century BCE.
Evolution and Relevant Literature - Lokayata dates back at least to the Vedic Age or earlier. Some scholars think it is associated with the earliest Ganges civilisation and primitive Indian folk beliefs.
In the latter 19th century CE, several thousand of a certain Sikh sect followed the same ideas with Lokayata.
