Chennai, Jan 25 (IANS): PMK founder S.Ramadoss condemned Kanchipuram Sankara Mutt's Junior Pontiff Sankara Vijayendra Sarasvati for not standing up when the "Tamizh Thai Vazthu" or song in praise of Mother Tamil was sung at a function here on Wednesday.

In a statement issued here, Ramadoss said the Tamizh Thai Vazthu is Tamils' "national anthem" and is sung at all government/education and functions in which state Governor and Chief Minister participates.

At the Tamil-Sanskrit dictionary release function held here, the Kanchipuram Sankara Mutt's Junior Pontiff was seen sitting with his eyes closed as if in meditation when the Tamil Thai Vazthu was played.

However, when the National Anthem was played, he stood up, resulting in a controversy that he had insulted the Tamil language.

The dictionary, compiled by BJP's National Secretary H.Raja's father, the late S.Hariharan, was released by Tamil Nadu Governor Banwarilal Purohit.

Ramadoss demanded Sarasvati express regret for his behaviour at the Wednesday's function.

Several other outfits have also criticised the Sankara Mutt's Junion Pontiff.
