 Sastri notes that this could be taken as evidence of one of the earliest migrations of people from North India into South, especially given that many Brahacharanam sub-sects have names such as Satyamangalam, Mangudi etc.- all names of villages hugging Western Ghats, and thereby denoting the route taken from North to South.It is to be noted however that Sastri considers this interpretation to be too speculative, given there is no direct evidence for the same.
