The Succession after Ramanuja.

According to the Tengalai accounts, Ramanujar appointed Parasara Bhattar his successor as Acharya. Bhattar wrote several Sanskrit hymns he also wrote in Sanskrit commentary on the ancient Vaishnava works the thousand names of Vishnu and a manual of daily worship.
The Vadagalai bographies state that Ramanujar appointed his Uncle Tirumalai Nambis son Tirukkuruhai Piran Pillan (Kuresa as his successor in the authoritative exposition of both the sanskrit and tamil scriptures. The very first of the written commentaries on the tamil hymns written in heavily sanskritized tamil is said to have been written by Pillan on the basis of Ramanujas own lectureson the hymn. earlier evidence however proves Parasara bhattar to be the successor. But it can be seen as a genius of Ramanujar that he set his disciples to different tasks depending on their talent and also his view of the needs of the community. today it however seems strange that the person who the northern school believe to be his successor had written the work assigned to him in Tamil and the Southern school believer  to have written in Sanskrit. and what goes to prove is that Ramanujar foresaw the change in the tradition of the teachings being orally handed down to be over taken by written literature. therefore he assigned his disciples duties so that each of them could see the greatness of both the Alwars works and the Vedic tradition to make it clear that he preached Ubhaya Vedanta. Ramanuja was not the originator of the traditions he articulated or the founder of the distictive sri Vaishnava community, but he had much to do with articulating those traditions in their synthesis in a way that made them known all over India and with the enlarging the Sri vaishnava community.
