Star of Stars.
Lord Maha Deva's star is embellished with
"Thiru" , meaning Maha, and is called
"Thiru-vadirai" in Tamil
Lord Maha Vishnu's star is adorned,
Again,with "Thiru" and is called
"Thiru-Vonam"
Then How can the star of Anusham
Be called as just Anusham
When it is the star of
Maha Periava,who is both
Maha Vishnu and Maha Deva?.
Hence the star of Anusham is now
Decorated with "Thiru" and
Is Re-christened as
"Thiru-Anusham".
