As Sri Lokacharyar did the great work called “SriVachana Booshanam”, SriAlagiaManavalaPerumal Nayanar wrote “SriAcharya Hrudayam” which very well explained many concepts of SriVaishnavism and SriVachanaBooshanam, the work of SriLokacharyar.
One day some persons who were hostile to SriLokacharya, told to SriNamperumal that “SriVachanabooshanam of SriLokacharya is very much against to our RamanujaDarsanam and Sampradayam and by this he spoils the SriVaishnavism”. By these words, Sri Namperumal send His servants and called SriLokacharya. At that time, he went to took bath and on behalf of him SriAlagia Manavala Perumal went in front of Sri Namperumal and the Lord enquired about the words of those people to him. Sri Alagia Manavala Perumal Nayanar explained the Acharya Hrudayam to the Lord and by this Sri Namperumal was pleased. HE offered Prasadams to Sri Alagia Manavala Perumal Nayanar and ordered His servants and temple staff to send Sri Alagia Manavala Perumal Nayanar in BrahmaRatham (a palanquin with the fans, garland and Sandal Paste of SriNamperumal) to his home. Sri Alagia Manavala Perumal Nayanar also wrote explanatory comments to Tiruppaavai of Sri Andal.
“Panavaal Aravanai palli payilvaarku evvuyirum
Guna Boghamenru Kurugaiku athipan uraitha thuyya
Unarpavinutporul onrum ariya ulagaria
Manavaalan maaran manamuraithan vanmudumbai vanthe”
The above song describes the greatness of Sri Acharya Hrudayam i.e., Acharya – Sri Nammazhwar(Maaran) Hrudayam – Manam. “Maran Manam”.
Other works of Sri Naayanar are:
a)Explanatory Comments to Amalanaadipiran of SriTiruppanazhwar
b)Explanatory Comments to Kanninun Siruthambu of Sri Madurakavi Azhwar
