To pray for Tamil Nadu Chief Minister Jayalalithaa, who has been in hospital for over a month, over 3,000 members of the ruling AIADMK joined a yagna or ritual in Chennai on Tuesday. Some 200 priests presided over the mass prayers. The "108 Mrityunjay Yagna" was organized by lawmaker R Vetrivel, a Jayalalithaa loyalist who has spent a fortune on prayers for his unwell leader.
