Hinduism is a religion (dharma) widely practiced in South Asia. Hinduism is considered one of the oldest religions in the world and some who practice it, as well as scholars, refer to it as Sanatana Dharma, "the eternal tradition", or the "eternal way", beyond the history of the humanity. Scholars consider Hinduism as a fusion or synthesis of various Indian cultures and traditions, with diverse roots and without any founder. This "Hindu syncretism" began to develop between 500 and 300 years before Christ, following the guidelines of the Vedic period.
