Hinduism is the biggest religion of the Indian subcontinent. It comprises four major traditions, Vaishnavism, Brahmanism, Shaktism, Shaivism,[1] whose followers consider Vishnu, Brahma, Shakti(Devi) and Shiva to be the Supreme deity respectively. Most of the other deities were either related to them or different forms (incarnations) of these deities. Hinduism has been called the "oldest religion" in the world, and many practitioners refer to Hinduism as "the eternal law". (Sanātana Dharma).[2] Given below is a list of the chief Hindu deities followed by a list of Hindu deities (including demi-gods). Smartism, an older tradition and later reestablished by Jagadguru Adi Shankaracharya, invites the worship of more than one god including Shiva like that, Vishnu, Brahma, Shakti and Ganesha (the elephant god) among other gods and goddesses. It is not as overtly sectarian as either Vashnavism, Brahmanism or Saivism and is based on the recognition that Brahman (God) is the highest principle in the universe and pervades all of existence.[3][4][5][6]
