The story of Kerala and its origin intwined with this Namboodri Brahmins. Parasurama after spending His wrath of having killed many Kshatriyas Kings in the North and South came to the Western Ghats and this mighty saint threw his axe to the Arabian Sea and called the Sea Lord to go back and gave him a strip of land which came to be known as Bhargava Kshetra, the present Kerala State. Parasurama brought Brahmins to settle there and asked Brahmins to develop this land which was so picturesque that many people came from the nearby States to inhabit it. This is the legendary origin of Kerala and the Namboodiri Brahmins and the peer among them is Adi Sankara.
