Thiru kurukaip piran pillan

The first acharya to write a commentary on any Sri Vaishnava work was Tiru kurukaip piran pillan, also known as pillan or kurukesha. He was born in Tirupati about 1062 A.D. Guruparamparaa prabhaavam accounts that, his father, Tirumalainambi, entrusted the boy's education to the care of Sri Ramanuja. Pillan studies Vedanta, Divya prabhandam and other Sastras under Sri Ramanuja.

Pillan wrote the first commentary on Tiru vAymozhi, known as Arayirap padi. This work consists of six thousand granthas, each made of 32 syllables.

Though Arayirap padi is the only know work of Pillan to this date, it is possible that he may have written more.
