Chattambi swamigal 

He is a goonda turned swami,who contributed nothing to the nair community.He was never an authority on anything.I would like to consider Ayyan kali much above him since Two Dalits(KR Narayanan and KG Balakrishan) could reach top positions in India as a result of the humble work started by him many decades ago.
Which are the old tamil texts he interpreted?The great tamil treatise,Thirukkural or chilappathikarm have no reference to nair.
