"Some Indologists labeled the Hinduism they encountered polytheistic; others even coined new terms, like henotheism, to describe this baffling array of spiritual traditions. Few, however, have realized, and fewer still have written, that India's Sanatana Dharma, or "eternal faith, " known today as Hinduism and comprising nearly a billion followers, is a family of religions with four principal denominations Saivism, Shaktism, Vaishnavism and Smartism. This single perception is essential for understanding Hinduism and explaining it accurately to others. Contrary to prevailing misconceptions, Hindus all worship a one Supreme Being, though by different names. For Vaishnavites, Lord Vishnu is God. For Saivites, God is Siva. For Shaktas, Goddess Shakti is supreme. For Smartas, liberal Hindus, the choice of Deity is left to the devotee."
