Sri ALavandhAr was the grandson of Sri Nathamunigal, who recovered for posterity the Naalaaiyra Dhivya Prabhandham as a result of NammaazhwArs anugraham.
ALavandhAr is also known as Yaamunaa Muni or Yaamunaaccharya. YAmunA is the grand -preceptor (PrAchAryA) of RaamAnujA. YAmunA established the principles of VisishtAdhvaitam as an expansion of the doctrines housed in his grandfather’s treatises: NyAya TattvA and Yoga RahasyA. He elaborated on those doctrines with authoritative scriptures such as Sruthis, Bhagavadh Gita, AzhwAr’s paasurams and selected SaatvikaPurAnAs.
