1205 CE. He is said to have lived for 106 years, during which time, he also helped to safeguard the idol of Ranganatha at Srirangam from Muslim invaders. Pillai Lokacharya confirmed the basics of the Sri Vaishnava system in his 18 monumental works popularly known as Ashtadasa Rahasyangal ("the eighteen secrets") also called the Rahasya granthas ("doctrines that explain the inner meanings") out of which Sri Vachana Bhushanam and Mumukshuppadi are the most famous. Manavala Mamuni expanded on and popularized Lokacharya's teachings arguments in Tamil. Traditions following Vishishtadvaita Sri Vaishnava Sampradaya of southern India Sri Ramanandi Sect of Northern India, it has the largest monastic order in whole India Dāmodariya Vaiśņava sampraday of Assam Swaminarayan sampradaya of Gujarat Visishtadvaita and Sri Vaishnavism The Absolute Supreme Reality referred to as Brahman, is a Transcendent Personality. He is Narayana, also known as Lord Vishnu. A man who has discrimination for his charioteer and holds the reins of the mind firmly, reaches the end of the road; and that is the supreme position of Vishnu. - 1.3.9 Katha Upanishad Beyond the senses are the objects; beyond the objects is the mind; beyond the mind, the intellect; beyond the intellect, the Great Atman; beyond the Great Atman, the Unmanifest; beyond the Unmanifest, the Purusha. Beyond the Purusha there is nothing: this is the end, the Supreme Goal.- 1.3.10,11 Katha Upanishad In terms of theology, Ramanujacharya puts forth the view that both the Supreme Goddess Lakshmi and Supreme God Narayana together constitute Brahman - the Absolute. Sri Lakshmi is the female personification of Brahman and Narayana is the male personification of Brahman, but they are both inseparable, co-eternal, co-absolute and are always substantially one. Thus, in reference to these dual aspects of Brahman, the Supreme is referred as Sriman Narayana in the Sri Vaishnava Sampradaya. The most striking difference between Srivaishnavas and other Vaishnava groups lies in their interpretation of Vedas. While other Vaishnava groups interpret Vedic deities like Indra, Savitar, Bhaga, Rudra, etc. to be same as their Puranic counterparts, Srivaishnavas consider these to be different names/roles/forms of Lord Narayan citing solid reasons thus claiming that the entire Veda is dedicated for Vishnu worship alone. Srivaishnavas have remodelled Pancharatra homas like Sudarshana homa, etc. to include Vedic Suktas like Rudram in them, thus giving them a Vedic outlook.
