I lived in Padmanaphapuram for more than 4 years. In front of the bus stand, there was a tree and a board under it like this: “This was the holy place where Guru Admananda met his own guru.”
I learned about Admananda after that and came to know that he was the teacher of the great pioneer of Tamil literature, K.Na.Subramanyam. My mentor and teacher, Sundara Ramasami, was a student of K.Na.Subramaniyam. So I can say I belong to Guru Admananda’s tradition. This video is a good introduction to him
