Namaskaaram to all the Vaishnavas!
All glories to the lotus feet of all Azhwars and Acharyas who have spread the glories of the Supreme Lord!
I am not well versed in the topic which I am about to address. But I definitely need help regarding this. I have heard that installation of Navagrahas in Vaishnavite temples is not according to Agama.
But recently, in Wikipedia I saw that Koodal Azhagar temple has a Navagraham, which is not found in Vaishnava temples.
So does this mean that the above mentioned temple has a different set of Agama rules?
