Hinduism is the largest religion in the Indian subcontinent, and the third largest religion in the world. It has been called the "oldest religion" in the world, and many practitioners refer to Hinduism as "the eternal law" (Sanātana Dharma).[1] Within this faith, there are four major traditions or denominations, namely, Vaishnavism, Shaivism, Shaktism, and Smartism.[2][3][4][5] There also exist a number of minor traditions, such as Ganapatism[6] and Saurism.
The religion is a diverse system of thought with a wide variety of beliefs, and hence the concept of God, and the number of deities, rests upon the philosophy and the tradition that make up a devotee's adherence. The faith is described by some to be monotheistic, where all deities are believed to be forms of Brahman, the Ultimate Reality, as popularised by the Advaita philosophy.[7] It is also widely regarded to be polytheistic and henotheistic, though this is also considered to be a form of overgeneralisation.[8]
