Adiyen,
To be honest, I observe that Telugu, Kannada and many parts of North Indians tend to be true bhaktha.
Coz of nAsthika attitude bhakthi is not patronized by Tamils…not all, except few..
Though majority tend to portrait as bhakthas in Tamilnadu, the are not truly dedicated as in other states mentioned above.bhakthi is being commercialised or exploited for commercial benefits.
In Kerala temples, priests strictly follow he aAcharam and nistai. This is completely missing in Tamilnadu, may be few exceptions ?
