The section on The Communion of Saints in the Tamil Saiva Tradition deals with most of the prominent features. I feel that reference to "the penetration of Brahmanic values such as the Agamic ritual tradition and individual liberation" as contributory factors to the decline of the saints' movement" and reference to Brahmanic Hinduism developing a social stratification on the basis of caste" could have been avoided. It is good to remember that great value is attached to 'Satsang' in the Sanskrit tradition. This recognition will in no way diminish the value in the Tamil tradition.
