In Srivaishnavism, the three important works are the rahasyams, thiruvAymozhi and SriRamayanam. Sri PVP stored the essence of these three in his mind and not only taught them to all his disciples, but also wrote vyakhyanams to them for the benefit of the vaishnavas yet to come. He is the person who wrote vyakhyanams for all the nAlAyira divyaprabhandam.
It is said in the AzhvarAcharya vaibhavams that for those in visishtadvaidam, there is no way beyond the divyaprabhandams, and that there is no better way to understand them outside of Sri PVP’s vyakhyanams. Therefore all Srivaishnavas are the disciples of Sri PVP.
After hearing his vyakhyanams Sri Ranganatha Himself gave him the name Abayapratharajar. By writing the essence of Ramayanam for us, he earned the title SriRamayanapPerukkar. Upon hearing his work, it was wondered if he was the reincarnation of Sri Valmiki.
Even though he was learned in Sanskrit he decided to write his vyakhyanams in maNipravALam (a mixture of Tamil and Sanskrit) so that everyone could understand them. He has written hundreds of works most of which are now unfortunately lost.
Periya Perumal, Periyazhvar, Periyavaccan Pillai and Periya Jeeyar all attained the title “Periya” due to their greatness.
It is wondered that did Krishna Dvaipayana who wrote sutras explaining the Vedas was reborn as Srikrishna- soori to explain the Tamil Vedas; was Sri Valmiki re- born as Abhayaprathrajar to bring out the thoughts in his heart; did Garuda who is the form of the Vedas was born as Sri PVP; did Sri Krishna Himself who churned the ocean of the Upanishads and brought out the nectar of Gita was reborn in His own birthday with His own name in rder to explain the caramasloka, prapatti and to churn the ocean of Azhvars works and bring out their nectar
