Swami Vivekananda (Bengali: স্বামী বিবেকানন্দ, Shami Bibekānondo (help·info); Hindi: स्वामी विवेकानन्द) (12 January 1863 – 4 July 1902), born Narendranath Dutta (Bengali: নরেন্দ্রনাথ দত্ত, Hindi: नरेन्द्रनाथ दत्त ), was the chief disciple of the 19th century saint Ramakrishna Paramahansa and the founder of the Ramakrishna Math and the Ramakrishna Mission. He is considered a key figure in the introduction of Indian philosophies of Vedanta and Yoga to the "Western" World, mainly in America and Europe and is also credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the end of the 19th century C.E. Vivekananda is considered to be a major force in the revival of Hinduism in modern India. He is perhaps best known for his inspiring speech which began: "Sisters and Brothers of America," through which he introduced Hinduism at the Parliament of the World's Religions at Chicago in 1893.
Hinduism is the predominant and indigenous religious tradition of the Indian Subcontinent. Hinduism is known to its followers as Sanātana Dharma (a Sanskrit phrase meaning "the eternal law", "the eternal law that sustains/upholds/surely preserves"), amongst many other expressions. Generic "types" of Hinduism that attempt to accommodate a variety of complex views span folk and Vedic Hinduism to bhakti tradition, as in Vaishnavism. Among other practices and philosophies, Hinduism includes a wide spectrum of laws and prescriptions of "daily morality" based on the notion of karma, dharma, and societal norms. Hinduism is a conglomeration of distinct intellectual or philosophical points of view, rather than a rigid common set of beliefs.
Hinduism is formed of diverse traditions and has no single founder. Among its direct roots is the historical Vedic religion of Iron Age India and, as such, Hinduism is often called the "oldest living religion" or the "oldest living major religion" in the world.
A large body of texts is classified as Hindu, divided into Śruti ("revealed") and Smriti ("remembered") texts. These texts discuss theology, philosophy and mythology, and provide information on the practice of dharma (religious living). Among these texts, the Vedas are the foremost in authority, importance and antiquity. Other major scriptures include the Upanishads, Purāṇas and the epics Mahābhārata and Rāmāyaṇa. The Bhagavad Gītā, a syncretistic treatise from the Mahābhārata, is of special importance. It combines Vedanta, Yoga, and some Samkhya philosophy into its discussion of good conduct and life.
