Tiruvaymoli is a masterpiece delineating the godly experience (Bhagavan Vishnu) of a true mystic. The study of this text with its commentaries is termed Bhagavad Vishayam as it explains the greatness of the Supreme Reality and his attributes. As per some scholars, it is also the study of the mystic Tamil outpourings known as Divyaprabandham. But more specifically, the term Bhagavad Vishayam specifically refers to an in-depth study of the commentary on Thiruvaimozhi, a second of Divyaprabandham, composed by Saint Nammalvar, who is the most important of the twelve Alwars in the Sri Vaishnava tradition.
Thiruvaimozhi is the magnum opus of Saint Nammalvar and it has inspired the commentaries of many Srivaishnava preceptors both in Sanskrit and in the manipravalam (colloquial) style. There are more than seven ancient commentaries available on this text. Of these, mention must be made of the commentaries by Thirukunnamangaipiranpillai which go by the name Arayirappadi, the commentary by Nanjiyar known as Onpadinayirappadi, the commentary of Periyavanapillai known as Impattunalayirappadi and the commentary of Nampillai called Idu.
In more than thousand poems, Saint Nammalvar in Thiruvaimozhi, has highlighted the transcendental nature of the God and His other such aspects. Though He is transcendental, yet He is easily accessible to a true devotee. This is the quality that human beings require in order to be saved from the cycle of birth and death. All attributes of Bhagavan that help one realize this aspect of human life is highlighted in Thiruvaimozhi.
Though the chief aim of the Alwar is to highlight the qualities of the Supreme, yet he depicts them by glorifying the 108 divya desams, that is, the select divine places and iconic forms present in those places. In addition to this, the Alwar glorifies the incarnations known as avataras of the Supreme and the deeds performed by him to highlight these qualities. All these points are well explained in the aforesaid commentaries of Thiruvaimozhi.
