Nampillai took over the reins of Srivaishnavism and its propagation from his preceptor Nanjiyar. He began delivering lectures on Nanjiyar’s onpatinayirappadi commentary on the Thiruvaimozhi in addition to adding his own examples and quotations from the scriptures. These lectures were transcribed on a palm-left by one of Nampillai’s disciples by the name Vadakku Thiruveedhi Pillai. When the latter submitted this commentary at the feet of his preceptor, Nampillai took possession of it as it was written without his permission. He then gave this commentary to another of his disciples by the name Eyunni Madhava Perumal at a later date. Eyunni Madhava Perumal taught this EDU commentary to this son Padmanabha Perumal. Padmanabha Perumal taught this to Nalur Pillai, who in turn taught his son Nalur Achan Pillai. The commentary finally reached Mamunigal’s preceptor Srisailesa through divine intervention in Lord Devaraja temple, Kanchipuram.
Stotra Ratnam is a hymnal composition of Svami Alavandar. It is a book of praises on the Lord – Narayana, the Supreme Brahman, in the school of the author. The traditional accounts consider the work to be an exposition of the core tenets of the Divya Prabandham of Azhvars, regarded as Dramidopanishad in Srivaishnava tradition.
At the outset, the author praises his spiritual master Svami Nathamuni in three hymns. Svami Nathamuni is identified as the eternal refuge both in this world and the next. The succeeding hymn praises Sage Parasara Muni, who is the author of the Vishnu Purana, for his contribution to the understanding of metaphysical realities. Svami Nammazhvar is praised next, and identified as the foremost master of his tradition. In Srivaishnava tradition, Svami Nathamuni and Svami Nammazhvar occupy positions before Svami Alavandar on the lineage of preceptors.
Upadesa Ratnamalai or ‘Jewel-studded Garland of Instructions’ is a work authored by Manavala Mamunigal in a classical Tamil form of poetry called venpa. A venpa is a metric prosody that ranges anywhere from two to twelve lines. This work appears to be an attempt by the author to educate the Srivaishnava community about: (i) The Glory of Alvars and Purvacharyas representing the tradition of Srivaishnavism; (ii) The commentaries authored by his earlier preceptors on the Divya Prabandham, (iii) The Greatness of the Tiruvaimoli and its commentaries, (iv) The tradition of Eedu Commentary of the Tiruvaimoli from Vadakku Tiruveedhi Pillai to Mamunigal himself, (v) The glory of Pillai Lokacharya’s srivachanabhushanam, (vi) Some instructions to Srivaishnavites on how to conduct themselves as worthy seekers of salvation and finally (vii) The revelation of ultimate means, Charamopayam.
