"This representation of Namam on the Vaisnava's forehead is known as Thirumann, which means the sacred earth (dust). Namam consists of three vertical lines joined at the base, the two outer white lines signifying the worship of Brahama and Vishnu and the red centerline signifying the worship Mahalakshi."
"During his lifetime Ramanuja wrote relatively few works compared to Sankara or Madhva, but what he did write had a major impact on the development of Vaisnavism in India. In fact Ramanuja has left us with nine works: Sri-bhasya, Vedanta-dipa, Vedanta-sutra, Vedanta-samgraha, three prose works (gadyas): Saranagati-gadya, Sriranga-gadya and Vaikuntha-gadya, the Gita-bhasya and Nitya-grantha. Unfortunately, Ramanuja wrote no commentaries on the Upanisads as did his colleagues Sankara or Madhva.
"The Sri-bhasya is Sri Ramanuja's magnum opus. It is his commentary on Bodhayana's Vedanta-sutra. It was completed when he was around a hundred years old. Here Ramanuja presents the fundamental philosophical principles of Visistadvaita based on his interpretation of the Upanisads, Bhagavad-gita and other smrti texts, the previous acaryas, and of course the Vedanta-sutra itself. This is done by way of refuting Sankara's advaita-vedanta and in particular his theory of maya. In his Sri-bhasya he describes the three categories of reality (tattvas): God, soul and matter, which have been used by the later Vaisnava theologians including Madhva. The principles of bhakti as a means to liberation (moksa) are also developed. The Vedanta-dipa and the Vedanta-sara are also commentaries of the Vedanta-sutra, although in more brief form.
"The Vedanta-samgraha is a summary of Ramanuja's views on the important Upanisads. In particular it is an exposition of the doctrines of categories of reality (tattva), the means to liberation, the goals of human life (purusarthas), the supremacy of Visnu and the powers of God. Next is Ramanuja's famous commentary of the Bhagavad-gita called the Gita-bhasya. In this work Ramanuja establishes the Supremacy of Visnu in the form of Krsna and discusses the details of bhakti-yoga, jnana-yoga, karma-yoga as the means to moksa. He also briefly discusses the Sri Vaisnava principal of prapatti or selfless surrender to God. The three gadyas are prose lyrics that also expound the doctrine of selfless surrender to God. Finally the Nitya-grantha explains the daily rituals and the mode of worship for Sri Vaisnavas. The writings of Ramanujacarya are most important because they provide a systematic account of the philosophic and religious principles of devotion for the first time in the history of Vaisnavism. Before Ramanuja's we only had pieces of such an approach. Ramanuja's writings also demonstrated how Vaisnavism could logically standup in the face of Sankara's advaita-vedanta."
The approach to the theology of monism as held by Sri Vaisnavas and Ramanuja is different. Sri Vaisnavas propose that ultimate Reality, although one, is not Absolute without any differentiation. They admit the reality of the world and the plurality of souls within this world. The world appears real because it is real and not due to some form of illusion (maya) as Sankara proposes. Accordingly Ramanuja teaches three fundamental categories of Reality: God (isvara), soul (cit), and matter (acit). On the basis of the principle of organic relation he upholds that ultimate Reality is one as a unity. God, as the creator of the world, is the immanent ground or inner soul of existence. God sustains and controls both the individual souls as well as matter. Soul and matter are dependant on God for their very existence and are organically related to God in the same way as the physical body is related to the soul within. The oneness of Reality is understood not in the sense of absolute identity, but as an organic unity. Though there is absolute difference between God and the other two categories of Reality, and for that matter between soul and matter, ultimate Reality is considered one because as an organic unity it is one. In this sense Ramanuja's philosophy may be defined as "oneness of the organic unity" (visistadvaita). More commonly visistadvaita is translated as "differentiated" monism (visistadvaita) as opposed to Sankara's absolute monism (advaita)."
