English annotation by Vishnudut1926: This is not original "Acharya Hridayam", but rather a set of various articles. Anyway, the Grantha is excellent.
The Chapter V ("Bridal Mysticism of Alvar and its philosophical interpretation") is truly unique - it contains amazing and rare explanations of jiva in the context of Bhagavan Shree Vishnu-Madhurya - very much recommended in case you are fond of Shringara-Rasa researches!!!
