Hinduism is a dharmic religion that dates back to the ancient Indus Valley Civilisation and Vedic time periods. Hinduism is often referred to as Sānatana Dharma by its adherents, a Sanskrit phrase meaning "the eternal law." A follower of Hinduism is known as a Hindu (Devanagari: हिन्दू) , which is a term derived from the river Sindhu, as an identification of the practitioners of the religion in ancient times who lived beyond the river.
Being a conglomerate of diverse customs, principles and beliefs over the time, Hinduism has no single founder; it is considered as the "oldest tradition" and "oldest religion" up to date.
Hinduism is today the predominant religion of the Indian subcontinent. It is the world's third largest religion after Christianity and Islam, with approximately a billion adherents, the most of whom are found in Pakistan, India, Nepal, Bangladesh and south to south-east Asia.
Concept of God
In Hinduism, the concept of God is a complex amalgamation. Hinduism is generally considered polytheistic (the belief and worship of multiple dieties) however such a view is overlooked when there are also multiple traditions spanning the ideologies of monotheism, pantheism, monism and even atheism. For instance, the Advaita Vedanta school holds that there is only one causal entity (Brahman), which manifests itself to humans in multiple forms while many scholars consider the Samkhya school to lean more towards atheistic learnings.
