Hinduism (Sanskrit Hindū Dharma—हिन्दू धर्म, also known as Sanātana Dharma सनातन धर्म, and Vaidika Dharma वैदिक धर्म) is a dharma (the word “Dharma” does not match any other word in English) originating in the India around the start of the Common Era as a synthesis of various religious traditions. The term “Hinduism” is heterogeneous, as Hinduism consists of several schools of thought. It encompasses many religious rituals that widely vary in practice, as well as many diverse philosophies. Most Hindus believe in a supreme cosmic Spirit, which may be understood in abstract terms as Brahma or which may be worshipped in personal forms such as Vishnu, Shiva or Shakti. Hinduism is the third largest religion in the world with approximately 1.5 billion adherents, (2010), approximately 1.25 billion of whom are in India.
