Hinduism is a conglomeration of distinct intellectual or philosophical points of view, rather than a rigid, common set of beliefs.
Hinduism is formed of diverse traditions and has no single founder. Among its direct roots is the historical Vedic religion of Iron Age India and, as such, Hinduism is often called the "oldest living religion" or the "oldest living major religion" in the world.
The earliest evidence for prehistoric religion in India date back to the late Neolithic in the early Harappan period (5500–2600 BCE). The beliefs and practices of the pre-classical era (1500–500 BCE) are called the "historical Vedic religion".
Hinduism refers to a religious mainstream which evolved organically and spread over a large territory marked by significant ethnic and cultural diversity. This mainstream evolved both by innovation from within, and by assimilation of external traditions or cults into the Hindu fold.
Hinduism grants absolute and complete freedom of belief and worship. Hinduism conceives the whole world as a single family that deifies the one truth, and therefore it accepts all forms of beliefs and dismisses labels of distinct religions which would imply a division of identity.
Hinduism is a diverse system of thought with beliefs spanning monotheism, polytheism, pantheism, monism, and atheism among others; and its concept of God is complex and depends upon each individual and the tradition and philosophy followed. It is sometimes referred to as henotheistic (i.e., involving devotion to a single god while accepting the existence of others), but any such term is an overgeneralization.
Most Hindus believe that the spirit or soul — the true "self" of every person, called the atman — is eternal.
