The term "Hindu" is derived from the river or complex river of the northwest, Sindhu, this is a Sanskrit word used by the inhabitants of the region, the Aryans in the second millennium BC, later migrants and invaders, the Persians in the century VI BC the Greeks from the fourth century BCE, and the Muslims of the eighth century CE, these in turn apply it to refer to the Earth and its people.
However, this term was used by people to differentiate themselves from the followers of other traditions, especially the Muslims (Yavannas), in Kashmir and Bengal. At that time the word may have simply indicated certain groups united by cultivation practices: such as cremation of the dead and cooking styles. 'Ism' was added to 'Hindu' only in the 19th century in the context of British colonialism and missionary activity.
The origins of 'Hindu' culture are just this way, political and geographic, now the terminology is widely accepted although any definition is subject to much debate. In a way, it is true that Hinduism is a religion of recent origin and even its formative roots go back thousands of years.
Some claim that he is 'born Hindu', but now there are many who are not Hindus of Indian descent, others claim that this characteristic is a central belief in an impersonal supreme but he described long notes of great importance on the worship of a personal God; outsiders often claim to be polytheistic Hindus, but many adherents claim to be monotheistic.
Some Hindus define orthodoxy as compliance with the teachings of the Vedic texts (the four Vedas and their supplements); however, others identify their tradition with ' Sanatana Dharma ', the eternal order of conduct that transcends any specific body of sacred literature. Scholars sometimes draw attention to the caste system as a defining feature, but many Hindus see such practices merely as a social phenomenon or an aberration from their original teachings; Nor can Hinduism be defined according to some concepts: such as belief in karma and samsara (reincarnation) because Jains, Sikhs and Buddhists (in a qualified way) accept the teaching as well.
