Later another attempt was made on Ramanuja's life while he was about to take charge of the temple affairs in Srirangam. The head priest of the Ranganathaswamy Temple, Srirangam did not like Ramanuja and decided to do away with him. Accordingly he invited Ramanuja to his house for having food and planned to kill him by poisoning his food. However, when Ramanuja arrived, the priest's wife saw the divine glow of Ramanuja and immediately confessed her husband's plan. This did not deter the priest who then made another attempt when Ramanuja visited the temple. He poisoned the temple "Theertham"(holy water) and served it to Ramanuja. However instead of dying Ramanuja began to dance with joy. The priest taken aback at once realised his mistake and fell at the feet of Ramanuja. The Sri Vaisnava tradition attributes nine Sanskrit texts to Ramanuja – "Vedārthasangraha" (literally, "Summary" of the "Vedas meaning"), "Sri Bhāshya" (a review and commentary on the "Brahma Sutras"), "Bhagavad Gita Bhāshya" (a review and commentary on the "Bhagavad Gita"), and the minor works titled "Vedāntadipa", "Vedāntasāra", "Gadya Trayam" (which is a compilation of three texts called the "Saranāgati Gadyam", "Sriranga Gadyam" and the "Srivaikunta Gadyam"), and "Nitya Grantham". Some scholars have questioned the authenticity of all but the three of the largest works credited to Ramanuja – Shri Bhāshya, Vedārthasangraha and the Bhagavad Gita Bhāshya. Ramanuja's philosophical foundation was qualified monism, and is called "Vishishtadvaita" in the Hindu tradition. His ideas are one of three subschools in Vedānta, the other two are known as Ādi Shankara's Advaita (absolute monism) and Madhvāchārya's Dvaita (dualism). Ramanuja accepted that the Vedas are a reliable source of knowledge, then critiqued other schools of Hindu philosophy, including Advaita Vedānta, as having failed in interpreting all of the Vedic texts.
