Atirudram and Sata Chandi Homam are considered as the highest form of worship to Lord Shiva
and Godmother Shakti and usually performed in conjunction. This great Yajnam ('Ati' means
"ultimate") is a destroyer of all sorrows, provider of 'Kshema' and is performed for ‘Loka Kalyana’,
good of humanity as well as to ensure peace & prosperity for all participating devotees. This eleven
day Mahayagnam is a rare opportunity to participate in or witness in one’s lifetime.
Atirudram is performed by 11 priests and 110 Ritviks chanting Sri Rudram 11 times per day for 11 days, thus making 14,641 recitations of Sri Rudram (14641 Namakams and 1331 Chamakams) during Rudra Japam and Homam. Each of Namakam and Chamakam consists of 11 sections called “Anuvakams”.
